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

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.

The phrase 'given the other a (iii) ________' requires a noun that represents a friendly gesture in a social setting. In peacetime settings like restaurants or bars, people might 'treat' each other - meaning to pay for something like a meal or drink as a friendly gesture. Option A 'shoot' makes no sense in a peaceful context. Option B 'enemy' contradicts the peacetime friendship described. Option D 'monetary' is an adjective, not a noun. 'Treat' here means buying something for someone as a gesture of goodwill.
