The correct option is C Recombination of genetic material occurs during mitosis.

Recombination of genetic material occurs during meiosis at the pachytene stage of prophase-I. Pachytene is the third stage of the prophase of meiosis, that takes place after zygotene, during which the paired chromosomes shorten and thicken, the two chromatids of each separate and exchange of segments between chromatids may occur.
