Answer & Solution
Correct answer: A. Artificial insemination and embryo transfer
1. Animal husbandry seeks better milk, meat and wool output.
2. The two main techniques used are artificial insemination and embryo transfer.
3. Tissue culture and apiculture relate to plants and bees; pisciculture and vermiculture relate to fish and worms; these do not match animal husbandry breeding.
