The correct answer is:
**B. It causes more variation in the traits of offspring.**
Chromosomal crossover occurs during meiosis when homologous chromosomes exchange genetic material. This process creates new combinations of genes, leading to increased genetic diversity in the offspring. This genetic variation is essential for evolution and can affect traits in numerous ways.
