Answer:
The correct answer will be option-D
Explanation:
Acid deposition is the process by which the acid formed in the atmosphere falls off with the rain and gets deposited in the lithosphere.
The deposition of the acid in the soil causes many adverse effects on the living organisms especially plants as deposition of acid leads to the reactions which result in the release of the elements from their compounds via a process known as "leaching".
The leaching of the elements leads to the decrease in the fertility of the soil and thus productivity of the plants or crops.
Thus, option-D is the correct answer.
