One of the TV cameramen was hit in the leg when they were caught in a(n) ______ of bullets outside the gang’s hideout. A. ice B. hail C. cloud D. storm

The correct answer is B. hail.

In this context, "hail" refers to a large number of bullets being fired at once, resembling the way hail falls from the sky. The phrase "caught in a hail of bullets" is a common expression used to describe a situation where someone is caught in a barrage of gunfire.

The other options do not fit as well:

A. "ice" is not typically used in this context and does not convey the idea of something falling or raining down.
C. "cloud" is generally used to describe something that is suspended in the air, not something that falls towards the ground.
D. "storm" generally refers to a natural weather phenomenon, and while one could conceptually think of a storm of bullets, it is not a commonly used phrase in this context.

Thus, "hail" is the most appropriate and idiomatic choice in this case.
