C. Crossing Over
Explanation:
Crossing over, also called recombination, is the process by which non-sister chromatids of homologous chromosomes exchange a segment of their chromosomal material with one another. The process of crossing over occurs only in the prophase I stage of meiosis.
The process is responsible for genetic variation in the gametes produced, thereby, leading to organisms that are genetically unique.
