Answer & Explanation

The correct answer is Option A: A) To create a barrier against radiant heat.

A water curtain, formed by a series of nozzles spraying water, creates a dense sheet of water. This acts as a thermal barrier, absorbing radiant heat and protecting adjacent areas or personnel from intense heat radiation, thereby preventing fire spread or providing a safe egress path.
