Answer:
The correct answer is: C) Heather wants to go to the store with us.
An infinitive is a verbal that can work as 3 different things: as a noun, as an adjective, or as an adverb. It is produced when using "to" + the verb, but this verb can't end in -ed, -ing or similar.
In this case, "to go" is the infinitive.
Explanation:
The infinitive is a linguistic term that refers to certain verb types that exist in various languages and is most commonly used as non-finite verbs.
An infinitive is a word that is generated from a verb but does not function as a verb. It can be used as a noun, adjective, or adverb and is made up of two words: to + verb.
These two terms function as a noun, adjectives, or adverbs when combined. Verbals are words that are formed from verbs but do not function as verbs themselves.
Thus Option C is correct.
