Answer:
B). Clyde had succeeded earlier in the same competition.
Step-by-step explanation:
As per the question, option B i.e. 'Clyde had succeeded earlier in the same competition' seems to be the most accurate as it appropriately that Clyde must have had the earlier experience of succeeding in the same competition because after witnessing a failure an individual requires sufficient motivational strength to regain the vigor to perform with full strength and succeed. Thus, Clyde must have gained this motivation and encouragement from her successful past experience to succeed in the competition which Sarah did not have and thus, she failed. Therefore, option B is the correct answer.
