Solution

The correct option is A Three
In S phase or Synthesis phase cell synthesizes a replica of the genome by the process known as DNA replication. It also includes synthesis of histone proteins and centriole duplication in the cytoplasm. Thus, the DNA content becomes doubled.
So the correct option is 'Three'.
