The man finally escaped . . . . . . . . his captors. A. of B. by C. over D. from

of
by
over
from

The correct answer is D. from.

The word “from” is the most common preposition used to indicate a separation or departure from a place or person. In this case, the man is escaping from his captors, so the preposition “from” is the most logical choice.

The other options are not as appropriate in this context. The word “of” is used to indicate possession or origin. The word “by” is used to indicate a means or method. The word “over” is used to indicate a position above or control of something.

In conclusion, the correct answer is D. from.
