Solution

The correct option is A 1 DNA molecule
During mitosis, anaphase stage is characterized by splitting of the centromere. The DNA molecule in each chromosome replicates in the synthesis or S phase of interphase and thus, it possess two DNA molecules. At anaphase stage, each chromosome splits at the centromere and each daughter chromosome thus produced is left with a single molecule of DNA only.
So, the correct answer is option A.
