Choose the most suitable option to replace the highlighted part of the sentence:
I suggested that he goes to the doctor immediately.

Correct option is C

The correct substitution of the highlighted words is (c) go to the doctor immediately.
Explanation: After verbs like suggest / recommend / insist / demand, we commonly use the structure that + subject + base form of verb (subjunctive). Therefore, “that he goes” is incorrect here; it must be “that he go.” This is a standard grammar pattern used to express advice, recommendation, or necessity. Hence, option (c) corrects the verb form and keeps the meaning unchanged.
Grammatical rule used:
· Suggest + that + subject + base verb (V1) (subjunctive)
· Example: I suggested that she take a break.
· Information booster / exceptions related to the topic:
· In informal English, you may also see: I suggested that he should go… (acceptable), but if “should” is used, the verb must remain base form ( should go, not should goes).
