Solution and Explanation

Step 1: Understanding the Question:

• Choose the correct combination of statements A to D.

• A is correct: humans lack the enzyme cellulase, so cellulose is not digested.

• D is incorrect: the branched polymer of glucose is glycogen in animals; in plants the branched polymer is amylopectin (starch).

• C is correct: the TCA cycle operates under aerobic conditions.

• B is accepted as correct in the NTA final key.

• Hence the combination is A, B and C.

Step 3: Final Answer:

As per the NTA final answer key, the correct option is (C) A, B and C only.
