Aallowed to drop naturally
Bmaintained at the normal level
Callowed to go out of sight
Dmaintained at a full glass
AI Explanation
The correct answer is B) maintained at the normal level. When a boiler has been secured and is being initially cooled, the water level in the steam drum gauge glass should be maintained at the normal operating level. This is to ensure that the boiler has adequate water coverage for the cooling process and to prevent any damage to the boiler components. Allowing the water level to drop naturally (A) or go out of sight (C) could lead to overheating and potential damage to the boiler. Maintaining a full glass (D) is unnecessary and could indicate an overfilled boiler, which is also undesirable.
