Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Embryogenesis refers to the process of development of embryo from the zygote. During embryogenesis, zygote undergoes cell division (mitosis) and cell differentiation. While cell divisions increase the number of cells in the developing embryo; cell differentiation helps groups of cells to undergo certain modifications to form specialised tissues and organs to form an organism. So, the correct answer is 'Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion'.
