Step 1: Understanding the Concept:
Safety at sea is regulated by international conventions, such as the International Convention for the Safety of Life at Sea (SOLAS).
These regulations specify the design and deployment of Life Saving Appliances (LSAs) on fishing vessels and ships.
Detailed Explanation:
- Analysis of Assertion (A): A life buoy (or ring buoy) is a personal life-saving appliance carried on board vessels.
It is classified under Life Saving Appliances (LSA) alongside life jackets, life rafts, and immersion suits.
Thus, Assertion (A) is true.
- Analysis of Reason (R): The primary purpose of a life buoy is to be thrown to a person who has fallen overboard into the water.
Its ring-like, buoyant design allows the person to hold onto it or slip inside it, keeping them afloat and preventing drowning until rescue arrived.
Thus, Reason (R) is true.
Because the reason explains *why* the life buoy is classified and used as a life safety appliance, it is the correct explanation for Assertion (A).
Step 2: Final Answer:
Both (A) and (R) are true and (R) is the correct explanation of (A), corresponding to option (1).
