Solution

(a). 24 chromosomes. Mitosis is the cell division in which chromosome number remains same in parent and daughter cells.
(b). 12 Chromosomes. Mitosis is the cell division in which chromosome number is reduced to half. Thus duaghter cell will have half number of chromosomes i.e 12.
(c). The DNA content at G1, S and G2 phase will be X, 2X and 2X respectively.
