The correct option is C Dynamic
The words "will take us forward" suggest that the quality that describes the man must be a positive one.
Option D: 'Dynamic' refers to a person who is 'positive in attitude and full of energy and new ideas'. It is most appropriate for this sentence, as the words 'new leader', 'young man' and 'take us forward' suggest. Hence option D is correct.
Option A: 'Haughty' means 'arrogantly superior' or snobbish. This isn't a positive quality and does not give the required meaning to the sentence. Hence A is incorrect.
Option B: 'Intoxicated' refers to thrill, enthusiasm. It is a state of one's mind or emotions that are short-term. For example, 'he was intoxicated by his own music'. It isn't appropriate here. Hence B is incorrect.
Option C: 'Fanciful' means 'highly imaginative' and 'unrealistic'. It isn't the desired quality here, hence D is also incorrect.
