Solution

The correct option is A
humus

Organic matter is formed by decay of plants and animals. When a plant drops leaves, twigs and other material on ground, it piles up and gets added to the animal matter. Over the time, all this breaks down into its most basic chemical elements. The layer of soil containing dead and decayed matter is called humus.
