Final answer:
The correct answer is C. Yusuf went to the Marina Circuit to participate in a car race, not to watch or check his engine without racing. He prepared by checking his engine upon arrival and started leading the race until an unfortunate collision occurred.
Step-by-step explanation:
Yusuf's purpose for going to the Marina Circuit was to participate in a car race, not merely to spectate or for any other reason. Upon arrival, although he did check his engine, this was likely a part of his preparation for the race, which started at eight. Unfortunately, his racing experience was marred by an incident where another car hit his from behind, leading to his vehicle's damage and his loss in the competition.
This circumstance left Yusuf feeling very disappointed, demonstrating the high hopes and personal investment he had in the racing event. Such an unwelcome turn of events undoubtedly impacted his mood and expectations for the day, manifesting in his frustration.
