Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understand the term:
A grill is a covering with openings placed at the end of a duct. Air enters or leaves the room through it.
Some grills have a damper or control valve behind them. The damper lets us adjust how much air passes.
Step 2: Recall the name:
A grill fitted with a damper or control valve is called a register.
A plain grill without a damper is just called a grill.
Step 3: Check option (A) and (B):
A filter removes dust from air. It is not a grill with a damper.
A fan moves air by its rotating blades. It is not a grill, so (B) is wrong.
Step 4: Check option (C):
A receiver is a vessel that stores liquid refrigerant in a refrigeration system. It has nothing to do with air distribution.
Final Answer:
A grill with a damper or control valve is a register. This is option (D).
