Detailed Solution

Ocean is a sink for $C O_{2}$ . Carbon dioxide dissolves easily in water, and the oceans contain a massive reservoir of carbon. Hence is sink for $C O_{2}$ .

But greenhouse effect results in the increase of temperature of earth’s surface not lowering.

To control the $C O$ emission by automobiles usually catalytic converters are fitted into exhaust pipes.

$H_{2} S O_{4}$ herbicides and insecticides from mist. Small water droplets suspended in air results in mist. It is artificially combined with aerosol canisters to form mist under suitable temperature conditions.

Therefore, option (D) is correct.
