The correct answer is: D. Baby
A cat is an adult animal of the species Felis catus, while a kitten is a young cat. Similarly, a woman is an adult human female, while a baby is a young human.
The other options are incorrect because they do not represent the same relationship as cat and kitten. A puppy is a young dog, a colt is a young horse, and a calf is a young cow. While all of these animals are young, they are not the same species as their adult counterparts.
In conclusion, the correct answer to the question "'Cat' is related to 'Kitten' in the same way as 'Woman' is related to: A. Puppy B. Colt C. Calf D. Baby" is D. Baby.
