Rewrite the following sentence using the correct tense of the verbs givenin the brackets:

Sanchit (standing) across the road and (wait) for me. When he (see) me, he (wave) to me. I could not understand what he (say) because the moving vehicles (make) so much noise.

The original sentence is in the past continuous tense, which indicates ongoing actions in the past. To maintain the same tense throughout the sentence, we need to use the past continuous tense for all the verbs.

Rewritten sentence:
Sanchit was standing across the road and was waiting for me. When he saw me, he waved to me. I could not understand what he was saying because the moving vehicles were making so much noise.

In the rewritten sentence, all the verbs are in the past continuous tense, ensuring consistency with the original tense of the sentence. The other options do not maintain the same tense throughout the sentence, making Option C the correct answer.
