Explanation

The correct answer to the question regarding the adjective form of 'ambition' is C) ambitious. The term 'ambition' is a noun that refers to a strong desire to achieve success or particular goals. In English, nouns often have associated adjectives that describe qualities or attributes relevant to that noun.

In this case, 'ambitious' is the adjective derived from 'ambition.' It describes someone who has a strong desire to succeed or achieve something, embodying the essence of ambition itself. For instance, saying "She is an ambitious person" directly conveys that the individual possesses a strong drive and determination to achieve their goals.

The other options do not serve as correct adjectives for 'ambition.' A) 'ambitive' is not commonly used in modern English. B) 'ambitionally' serves as an adverb, which relates to how something is done but does not convert to an adjective. D) 'ambigious' appears to be a misspelling of 'ambiguous,' which means unclear or vague and is unrelated to the concept of ambition. Therefore, 'ambitious' stands out as the appropriate and recognized adjective form of the noun 'ambition.'
