**The reasoning**
Animal husbandry is literally in the name! Let's break it down: "animal" + "husbandry" (which means care and management). So animal husbandry is the **science and practice of breeding, feeding, and caring for farm animals** to produce food, fiber, and other products. Think of poultry farming, cattle rearing, piggery, goat farming — all the livestock you see on Nigerian farms. The farmer is managing *animals* for production purposes.
**Why the wrong options tempt you**
**A) Plants** — That's crop production or agronomy, not animal husbandry.
**C) Fish only** — This is too narrow! Fish farming is called *aquaculture* or *pisciculture*. Animal husbandry covers all livestock (cattle, goats, chickens, etc.), not just fish.
**D) Crops** — Again, that's crop farming/agriculture, a different branch entirely.
**Quick takeaway**
Remember: **Animal husbandry = Animal care and management.** Anytime you see "husbandry," think livestock farming — chickens, cows, pigs, goats — everything with legs (and wings!), not plants or only fish.
