The correct answer is D.ammonification.

Ammonification is the process by which decomposers like fungi and bacteria break down dead organic matter (such as plants, animals, and waste material) and convert nitrogen from these organic materials into ammonia (NH₃) or ammonium ions (NH₄⁺). This ammonia can then be used by plants or further processed in the nitrogen cycle.

Here’s a brief explanation of the other terms:

A.Nitrification: This is the process by which ammonia (NH₃) or ammonium (NH₄⁺) is converted into nitrates (NO₃⁻) by nitrifying bacteria in the soil. Nitrification follows ammonification in the nitrogen cycle.
