Detailed explanation-1: -The interphase is the period when the cell is in a non-dividing state and this can be in different stages: the first gap (G1 ) between the last mitosis and the S phase (phase of DNA synthesis) and the second gap (G2) between the completion of the S phase and the next mitosis (M).

Detailed explanation-2: -Answer and Explanation: The correct answer choice is C. The nucleus replicates. Replication of the nucleus does not happen during interphase.

Detailed explanation-3: -A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.

Detailed explanation-4: -Answer and Explanation: Cell that are not dividing are said to be in G0 (quiescent) state.
