Answer:
D) whatever his father cooks.
Step-by-step explanation:
In English language, a noun can be defined as a word used to refer to a person, place, animal, idea, feeling or thing. Therefore, a noun is considered to be a naming word.
Also, a clause can be defined as a group of words that comprises of both a subject and predicate (finite verb).
A noun clause can be defined as a dependent clause which acts as a noun by taking its place in a sentence.
Generally, noun clause begins with a subordinating conjunction such as how, when, where, whether, why, whomever, what, that, whatever, etc.
This ultimately implies that, a noun clause can act as a predicate nominative, direct object, object, indirect object, or subject of a preposition.
In this scenario, the most appropriate noun clause to fill in the blank is "whatever his father cooks."
Hence, the complete sentence would be written as;
"Mike will eat whatever his father cooks tonight."
