Solution

The correct option is C Prophase I during meiosis
Crossing-over occurs during prophase I of Meiosis I. In this stage of meiosis homologous chromosomes form chiasmata (singular: chiasma) or intersection points between them. After the formation of chiasmata at different points, the members (chromosomes) of the homologous pair exchange chromosomal segments with each other.
