Answer

Brief Explanations:

Parentheses are used to set off non - essential information. In the original sentence, "but the one he had trained for the hardest was the 400 - meter competition" is an important contrast and not non - essential. None of the options with parentheses are correct as they disrupt the natural flow of the sentence. The original sentence is already well - formed and does not need the use of parentheses for better clarity.

Answer:

None of the above options are correct as the original sentence is best as it is without the need for parentheses.
