Despite his initial hesitation, Rehman’s ______ to contribute to the success of the project never wavered.

Select the most appropriate option to complete the above sentence.

The correct option is resolve.

Step-by-step Explanation:

1. Understand the Sentence Context: The sentence begins with the word "Despite," which indicates a contrast between Rehman's "initial hesitation" (his starting doubt or reluctance) and a quality that "never wavered" (remained completely firm and steady) regarding his contribution to the project's success.
2. Analyze the Options:
- resolve (noun): This means firm determination or a fixed purpose. A person's determination or "resolve" is a quality that can stay strong and "never waver." This fits the sentence structure and meaning perfectly.
- ambivalence (noun): This means having mixed, contradictory, or undecided feelings. If Rehman's attitude never wavered, he could not be described as having ambivalence.
- satisfaction (noun): This refers to the fulfillment of expectations or needs. One's "satisfaction to contribute" does not make semantic sense in this context.
- revolve (verb): This is a action verb meaning to turn around an axis, which does not grammatically fit the possessive noun phrase "Rehman's ______."
3. Conclusion: Therefore, resolve is the most appropriate option to complete the sentence, indicating that his determination to help make the project successful remained steady despite his early hesitation.
