The correct answer is B. escaped.
The thieves left her tied up with rope, but she wriggled herself free. This means that she managed to get away from the thieves, even though she was tied up. She did this by wriggling, which is a type of movement that involves twisting and turning the body. This movement allowed her to loosen the ropes and eventually get free.

This does not accurately describe what happened in the sentence, because the woman did not create or produce anything. Option D, allowed, means to give permission for something to happen. This does not accurately describe what happened in the sentence, because the thieves did not give the woman permission to get away.
