Kedu ihe okwu ọkụkọ na-akọ? .

The question asks what the word okuko refers to. In Igbo, "okuko" means a chicken or domestic fowl (hen or rooster). A chicken is a type of animal, specifically a domesticated bird commonly reared for eggs and meat in Igbo communities and across Nigeria.

The correct answer is Anumanuu (animal). A chicken falls under the broad category of animals (anumanuu), which in Igbo usage encompasses all creatures including birds, mammals, reptiles, and insects.

The other options are incorrect: "Ulo" means a house or building, "Nkwu" means a palm tree, and "Ugbo ala" means a car or vehicle. None of these describe a living creature. The word "okuko" is one of the most common animal-related vocabulary words in Igbo and is frequently tested at this level.
