For good health, she . . . . . . . . bed earlier. A. should goes to B. should goes C. should go to D. should go

The correct answer is: D. should go

The verb “go” is conjugated correctly in the simple present tense, which is the tense that is used to express general truths or habits. The infinitive form of the verb “go” is “to go,” so the correct conjugation is “should go.”

The other options are incorrect because they are either not conjugated correctly or they do not make sense in the context of the sentence.

• Option A: “should goes” is not a grammatically correct sentence. The verb “goes” should be conjugated to agree with the subject “she,” so the correct sentence would be “she should go.”
• Option B: “should goes to” is also not a grammatically correct sentence. The preposition “to” is not necessary after the verb “go.” The correct sentence would be “she should go.”
• Option C: “should go to” is grammatically correct, but it does not make sense in the context of the sentence. The preposition “to” is used to indicate a destination, but the sentence does not specify a destination. The correct sentence would be “she should go to bed earlier.”
