Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

According to page 4, chemosynthesis 'does not require light as an energy source. Energy is obtained by chemical reactions within the cell.' It also states that 'Chemotrophs do not use water as the donor of hydrogen to reduce CO2, therefore, oxygen is not liberated in the process.'

Hint

Consider the origin of 'chemo' in chemosynthesis.
