The correct answer is: Four times DNA content but double chromosome number
The DNA content will be four times and the chromosomes will be double in number in a cell after S - phase as compared to the gamete of the same organism.
Gametes are haploid(n) cells that contain one set of chromosomes and half amount of DNA content in it.
During S- phase of cell division, only the DNA content of cell gets doubled from 2 n to 4 n while number of chromosome remain same in the dividing cell.
