What word is related to a doe?

The term "nanny" refers specifically to a female goat, which is analogous to the relationship between a doe and a buck. In terms of animal classifications, a doe is a female deer, and a counterpart to this would be a male deer, known as a buck. While "nanny" pertains to a different species, the connection lies in the terminology used for female animals, similar to how female and male deer are referred to in the context of their species.

The other options relate to different animal species or different contexts: a kid refers to a young goat (the offspring of a nanny), and hind typically describes female deer but is not a direct counterpart like buck is to doe. Therefore, while "nanny" is indeed a term for a female animal, it's predominantly associated with goats, indicating a broader understanding of animal terms rather than a direct relationship to a doe.
