Brennan Larsen · Answer 1

Option A

Explanation:

The rate and amount of decomposition of alcohol depends on the amount of body fat in an individual. The activity of enzyme alcohol dehydrogenase that breaks down alcohol is affected by concentration of body fat and water.

The higher the body fat and the lower is the body water and fluid, the higher is the activity of enzyme alcohol dehydrogenase.

Thus, the higher activity of enzyme alcohol dehydrogenase ensures higher rate of breakdown of alcohol due to which level of alcohol concentration in blood of an individual reduces.

Hence, option A is correct
