Answer

Soln:

The answer is (b) Topsoil

Explanation:

Topsoil is rich in humus and consists of decaying remains of plants and animals. Humus improves the texture of the soil and provides nutrients for plant growth. So, it is the most fertile region and soil conservation measures are mainly aimed at protecting topsoil. If topsoil is protected or conserved, then subsoil is also conserved as it lies below the topsoil.
