Solution

The correct option is C 12
In G2 phase, also called as second growth phase or pre-mitotic gap phase, the DNA synthesis stops after doubling in the S-phase. So even though the DNA content has doubled after the cell division the chromosome number will still remain 12 in the G2 phase of its next cell cycle.
