Identify the segment in the sentence which contains a grammatical error.
There were some team members who do not agreed to the coach’s suggestions about changing their strategy.

Correct option is A

Option (a) contains an error.
Explanation: The phrase “do not agreed” is incorrect because it combines a present auxiliary verb “do” with a past verb “agreed”, which is grammatically incorrect. The correct form should be either “do not agree” (present) or “did not agree” (past), depending on the tense of the sentence. Since the sentence begins in the past (“There were”), the correct verb form is “did not agree”.
(Hindi explanation – “do not agreed” गलत है; सही होगा “did not agree”)
Corrected Sentence:
There were some team members who did not agree to the coach’s suggestions...
Grammatical Rule Used:
· After auxiliary verb "do/does/did", always use base form of the verb.
· Match the tense of the relative clause with the main clause. Both should be in past if the event happened in past.
Example:
Incorrect: They do not went to the party.
Correct: They did not go to the party.
