Answer 1

The right option is; a. soil degradation

Soil degradation most plausibly accounts for the reduction in corn yield.

Soil degradation is an environmental problem in which the condition or quality of soil is reduced due to its improper use usually for agricultural or industrial purposes. Soil degradation can reduce the physical, chemical and biological quality of soil. Soil degradation results in loss of organic matter, soil contamination, fertility decline, and soil acidity or alkalinity which can greatly affect agricultural productivity.

The correct option among all the options that are given in the question is the first option or option "a". I hope that this is the answer that has helped you.
