The question asks for the adjective form of the noun "home." Among the provided options, "homely" (option C) is the correct answer.

The word "homely" is an adjective that describes something as being characteristic of home; it conveys a sense of warmth, comfort, or simplicity often associated with domestic spaces. While "homely" can sometimes imply being plain or lacking sophistication, it ultimately relates to the feeling of being at home, which aligns well with the concept of "home."

The other options do not correctly serve as adjectives describing "home."

- Option A, "home-like," is not commonly used and sounds awkward, although it technically conveys a similar idea.
- Option B, "homeful," is not a standard word in English; it is largely unrecognized and doesn't effectively convey a relevant meaning.
- Option D, "homage," is a noun that refers to respect or allegiance and does not relate to the concept of home at all.

Thus, "homely" is clearly the most appropriate choice, as it correctly transforms the noun "home" into a well-established adjective that evokes the essence of home.
