Directions: Choose the most appropriate word to fill the blank (ii)

Two soldiers of rival forces treat each other as an (i) ________ and are prepared to (ii) ________ each other down. However, had the two met each other in peacetime at say a restaurant or a bar, one might even have given the other a (iii) ________ or offered (iv) ________ help.

In the context of rival forces at war, soldiers are prepared to 'shoot' each other down. The phrase 'shoot down' means to kill with gunfire, which fits the wartime context of enemy soldiers. Option A 'treat' doesn't make sense because you don't 'treat someone down'. Option B 'monetary' is an adjective related to money, not a verb action. Option C 'enemy' is a noun naming what they are to each other, not what they do to each other. The correct structure requires a verb that can follow 'down' and means to eliminate or kill.
