A somatic cell that has just completed the S phase of its cell cycle, as compared to a gamete of the same species, has?

The somatic cells are diploid and undergo mitosis to form two cells with the same amount of genetic material. In the S-phase, the amount of DNA replicates to produce two copies which can be distributed among the two daughter cells. The amount of DNA and the number of chromatids gets doubled but the number of chromosomes remains the same. So, the cell after the S-phase will have the same number of chromosomes but twice the amount of DNA. Thus, the correct answer is option C.
