Quoting "Return of the Jedi" Trivia Quiz

Answer: C-3PO

At the beginning of the movie, C-3PO spoke to Jabba the Hut and played a hologram, courtesy of R2-D2, which had a recording from Luke Skywalker. In the recording, Luke told Jabba the Hut that he was leaving two droids, C3PO and R2-D2, in his care as a gift. Shortly after this, C-3PO asked himself what could be the matter with Luke, to place him and R2-D2 in Jabba's hands.

Answer: Carbonite

Jabba had Han's body at his place and it was still frozen in carbonite, at the beginning of the movie. Leia, who donned a get-up to get past his guards, pushed some buttons to defrost Han and he became free. When he started to shiver, Leia told him to relax since he was free of the carbonite.

Answer: True

Near the end of the movie, Luke did battle with his father, Darth Vader, and he got the upper hand at one point in the fight. The Emperor was nearby and continued to try and persuade Luke to join the dark side. Luke told him that he would never turn to the dark side, since he was a Jedi, like his father before him.

Answer: Jabba the Hutt

Right as Leia was about to escape with Han, they were confronted by Jabba the Hut and his men. Jabba had his men deal with Han while he asked that Leia be brought to him. Leia warned Jabba that she had powerful friends and he would regret what he was doing.

Answer: Han Solo

At the end of the movie, Han and Leia were talking about Luke and hoping he was not on the Death Star when it exploded. Leia mentioned to Han that she believed Luke was not on it since she could "feel it". Han falsely assumed that Leia was in love with Luke, so he told her that he would not get in the way of them being together. Leia laughed and informed Han that her love for Luke was nothing romantic, since Luke was her brother.

Answer: Lando Calrissian

During the big fight scene, near the beginning of the movie, a creature known as Sarlacc grabbed Lando Calrissian's leg and was about to drag him towards his stomach to digest him, so Han grabbed a gun to help. Han told Lando to watch out since he was going to use the gun to shoot the Sarlacc but Lando yelled back to Han that he thought he was blind and therefore might shoot him instead. Han managed to shoot the Sarlacc and save Lando.

Answer: False

Luke went to Dagobah so he could visit Yoda and it was there that they had a long talk. Yoda said he was weak, old and not feeling well. Yoda laid down and informed Luke, during their talk, that the force ran strongly through his family and that he hoped Luke would pass on what he learned. Yoda then died and disappeared.

Answer: Obi-Wan Kenobi

After Yoda died, Luke got a visit from Obi-Wan Kenobi's spirit. Obi Wan told him that Yoda would always be with him. Luke then spoke to Obi-Wan about Darth Vader and Obi-Wan told him he had to confront Darth Vader in order to be considered a true Jedi Knight. Obi-Wan mentioned to Luke that he had a twin sister and Luke realized that Leia was his twin sister.

Answer: Darth Vader

Midway through the movie, Darth Vader went to talk to the Emperor. During their talk, Darth mentioned that Luke and his friends were on a forest moon known as Endor, (as in the place where the Ewoks lived). The Emperor asked Darth Vader if he was sure so he responded that he could feel Luke's presence there.

Answer: C-3PO

Midway through the movie, the Ewoks captured Luke, Han, R2-D2 and Chewbacca; C-3PO was present during this. The Ewoks bowed at C-3PO's feet so Han asked C-3PO if he could make out what they were saying. C-3PO said he was unsure but he assumed the Ewoks thought of him as some God.
