Select the most appropriate option to fill in the blank.
We would _______to travel by train rather than bus due to the poor road conditions in the village.

Correct option is A

The correct option is (a) prefer.
The sentence is looking for a verb that fits logically with choosing to travel by train over bus. "Prefer" is the most appropriate word, as it signifies a choice or inclination toward one option over another.
Meanings of Other Options:
 Assure: To promise or say with confidence. It does not fit here because the sentence is talking about a preference, not a guarantee or promise.
 Makeit: To succeed in achieving or accomplishing something. It doesn't fit the context of a choice between two modes of transportation.
 Drop: To let go of something or discontinue. In this context, it does not make sense to "drop to travel by train."
