Solution
The correct option is C Assertion is correct but Reason is incorrect
The mitotic division called cleavage starts as the zygote moves through the isthmus of the oviduct towards the uterus and forms 2, 4, 8, 16 daughter cells called blastomeres. The embryo with 8 to 16 blastomeres is called a morula. The morula continues to divide and transforms into blastocyst as it moves further into the uterus. The blastomeres in the blastocyst are arranged into an outer layer caned trophoblast and an inner group of cells attached to trophoblast called the inner cell mass.So, the correct answer is 'Assertion is correct but Reason is incorrect'.
