Which of the following is a disadvantage of using biopower?

A. It requires mass production of crops.

B. It is readily available in most places.

C. It produces net-zero emissions.

D. It is biodegradable

A. It requires mass production of crops.

Explanation:

Of all the options the only one that represents a disadvantage is that biopower requires mass production of crops because it could cause loss of biodiversity, degradation of soil quality, soil erosion, food toxicity (due to pesticide residues) and pollution (use of fossil fuels for agrichemical manufacture, farm machinery and long-distance distribution).

The fact that it is readily available in most places, produces net-zero emissions and is biodegradable are all advantages.
