The correct answer is option C, that is, it prevents the formation of ATP and NADPH, which are needed by the light-independent reactions to make sugars.
The herbicide atrazine combines with the D1 protein and inhibits the binding of plastoquinone. By obstructing the binding of plastoquinone, the procedure of photosynthetic transfer of electron is disturbed, and thus, the production of ATP and NADPH in the chloroplast gets compromised.
This leads to an incapacity to fix carbon dioxide and generate the nutrients required for the plant to live. The block in the transfer of electrons also results in an oxidative stress and the production of radicals that lead to brisk cellular destruction.

Genetic drift is a process in which allele frequencies within a population change by chance alone as a result of sampling error from generation to generation. Genetic drift is a random process that can lead to large changes in populations over a short period of time.
Answer:
The correct option is B. Fermentation would occur at a similar rate to that of glucose.
Explanation:
Fermentation can be described as a process in which alcohol is released by using sugars. In fruit juices, fructose is present mainly to get the sweetness. It is used as a substitute for glucose because fructose is more sweeter than glucose. Both fructose and glucose are monosaccharides with the formula C6H12O6. The only difference is in the arrangement of molecules in the atoms of these compounds. Hence, the rate of fermentation would be same for these two sugars.
