b) Biodegradable waste is the main cause of soil pollution.
c) Soil contamination is a part of land degradation.

• A. Only A
• B. Both A and B
• C. Only C
• D. A, B and C

Answer 1

The correct option is C Only C

The trash is mainly composed of the papers and the cardboard. These components contain the cellulose and can be degraded by the activity of the microorganisms. These products do not cause soil pollution.

Biodegradable is the waste which can be degraded by the activity of microbes. They are converted into elements which get mixed with the soil. These sources are not the cause of soil pollution.

When there is a change in the soil fertility and the composition of the soil contains toxic and harmful compounds, the soil is said to be contaminated. The contaminated soil reduces the fertility and productivity of the soil. The land gets degraded and cannot be used for production purposes.

Thus, the correct answer is option C.
