Answer:
D) asexual reproduction.
Explanation:
Cloning means copying and possessing exactly the same genetic material as the original organism bears. Cloning occurs naturally by asexual reproduction, that is a process in which a single organism creates a genetically identical copy of itself. Asexual reproduction needs only one parent, unlike sexual reproduction, which needs two parents. As a result, the offspring are genetically identical to the parent and to each other and hence they are called clones.
