Solution

The correct option is D Both B and C
Interphase generally lasts at least 12 to 24 hours in mammalian tissue. During this period, the cell is constantly synthesizing RNA, producing protein and growing in size.
Gap 1 (G1): Cells increase in size in Gap 1, produce RNA and synthesize protein.
Gap 2 (G2): During the gap between DNA synthesis and mitosis, the cell will continue to grow and produce new proteins.
Hence answer is 'Both B and C'
