The correct answer is C. unwilling.
The word “reluctant” means “unwilling or hesitant to do something.” In this case, the young leader is hesitant to take on the responsibilities of the ministerial office. This could be because they feel they are not qualified for the job, or because they do not want the added stress and responsibility.
The other options are incorrect because they do not accurately describe the young leader’s feelings. Option A, “eager,” means “feeling or showing great interest or enthusiasm.” Option B, “anxious,” means “feeling or showing worry, nervousness, or unease.” Option D, “wanting,” means “having a strong desire for something.”
It is possible that the young leader is also feeling some of these other emotions, but the word “reluctant” is the best word to describe their overall attitude towards the ministerial office.
