How did Lancelot escape from the four witches?

Merlin realized that Lancelot was in trouble and appeared before him telling him of a secret passage to escape through.

After the “evil eyes” had finished attacking him, he was visited by kind spirits who delivered the dungeon keys to him.

One of the four witches who had captured him had a change of heart after seeing him suffer under the “evil eyes” torment.

A chambermaid helped him escape on his promise that he would rescue her father and release her from Queen Morgan le Fey

D?

I agree.

thank you

You're welcome.

Based on the given options, it seems that Lancelot escaped from the four witches with the help of a chambermaid. Lancelot made a promise to the chambermaid that he would rescue her father and release her from Queen Morgan le Fey in exchange for her assistance in escaping.
