NEET 2015 Biology question

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

(1)same number of chromosomes but twice the amount of DNA
(2)twice the number of chromosomes and four times the amount of DNACorrect
(3)four times the number of chromosomes and twice the amount of DNA
(4)twice the number of chromosomes and twice the amount of DNA

Answer: (2)
