Solution

The correct option is C Assertion is correct but Reason is incorrect.
Cross pollination is helpful in making strong and sturdy progeny. It ensures the mixing of genes in the gene pool and thus, result in the mixing up of characters. New varieties are produced by the method of cross-pollination. In this case, the pollinators like insects, birds, water, air etc., will cause the pollen grains to fall on the stigma of a different type of flower in some cases and thus causes variation.
So, the correct answer is option C.
