Answer is D. Just took the test:)

D. Mustufa ran the 100-meter and 200-meter races (but the one he had trained for the hardest was the 400-meter competition).

Step-by-step explanation:

We are given the sentence,

'Mustufa ran the 100-meter and 200-meter races but the one he had trained for the hardest was the 400-meter competition'.

It is required to re-write the sentence with the best revision possible.

Now, as we know,

Parentheses are used to add information for clarity or to add the extra information provided.

Thus, this extra information is not a part of the discussion.

Here, the main part of the sentence is that 'Mustufa ran the 100 and 200 meter races', whereas the extra information is 'He trained hardest for the 400 meter race'.

Thus, the correct revision of the sentence will be,

D. Mustufa ran the 100-meter and 200-meter races (but the one he had trained for the hardest was the 400-meter competition).
