Explanation:

Question 3

Acid rain is formed when pollutants like sulfur dioxide and nitrogen oxides from power plant smoke combine with moisture in the air, leading to the formation of acidic compounds that fall as rain. Sleet is a type of frozen precipitation, sour rain is not a correct term, and smog is a different type of air pollution involving fog and pollutants but not specifically from power plant pollutants combining with moisture to form acidic rain.

Smog (specifically photochemical smog) is formed when chemicals in car exhaust (like nitrogen oxides and volatile organic compounds) react with sunlight. Acid rain is from pollutants combining with moisture, the greenhouse effect is about heat trapping gases, and contaminant fog is not a standard term.

Answer:

C. Acid rain
