The answer is C: Cloning
The correct answer is the third option. The process where the goal is to produce a baby cow with DNA that is identical to the first cow is called cloning.
This scenario describes the process of cloning. Cloning involves creating an organism with the same genetic makeup as another organism. In this case, the scientist is attempting to create a baby cow with DNA identical to the first cow by transferring the DNA from the first cow's cell into the egg of the second cow.
This process aims to produce an offspring that is a genetic replica of the original cow.
