Correct answer: D) reproductive cloning
The cell technology that was possible by the micromanipulation tools is reproductive cloning. It is a form of artificial reproduction that uses the cloning technique.
It involves creating an animal that is genetically similar to a donor animal by the somatic cell nuclear transfer technique. In this cloning, the newly produced embryo is put back into the uterus where it can implant and develop further. There are two types of reproductive cloning by cleavage and cloning by the transfer of a cell nucleus into an enucleated ovum.
Hence, the correct answer would be option D.
