The correct option that results in genetic variation in body cells is **mutations caused by environmental factors**.
While crossing over and meiosis primarily contribute to genetic variation in gametes (reproductive cells), mutations can occur in body cells (somatic cells) due to various environmental influences, leading to genetic variation in those cells. Errors during gamete DNA replication can also introduce variation, but they are less relevant to body cells specifically.
