The correct answer is:
Twice the number of chromosomes and four times the amount of DNA
S-phase (synthesis phase) is the part of the cell cycle in which DNA is replicated, but a number of chromosome does not change.
If a cell is diploid then after S phase DNA content in the cell will be 4 C and Chromosome in the cell will be 2 N.
While in a gamete,
DNA content in gamete = C
Chromosome in gamete = N
Hence, the Number of chromosome in a somatic cell will be twice than gamete while DNA content will be four times.
