Select the sentence that has a grammatical error.

Correct option is C

Option (c) contains an error.
The subject "Indian force" is grammatically incorrect. The plural noun "forces" should be used instead of the singular "force", as the context refers to the entire military or armed forces, which is a plural entity. Additionally, the verb "are" is correct, but it must agree with the plural subject "forces."
Correct sentence: Indian forces are known for their loyalty and integrity.
Grammatical Rule Involved:
1. Subject-Verb Agreement:
· The subject and verb in a sentence must agree in number (singular/plural).
· In this sentence, "force" (singular) does not align with the plural verb "are", creating an error.
2. Collective Nouns:
· When referring to the military, the term "forces" is used to indicate the armed forces or military units collectively.
Examples to Clarify the Rule:
· Correct Usage: The Indian forces are deployed at the border.
· Incorrect Usage: The Indian force are deployed at the border.
Why Other Options are Correct:
· (a) It is said that Joseph was not ready to go to war: Grammatically correct. The sentence is properly structured with correct subject-verb agreement and tense.
· (b) Karl Marx was a renowned social scientist: Grammatically correct. The sentence is correctly constructed in past tense with no errors.
· (d) It is impossible to wake Christine up in the morning: Grammatically correct. Proper subject-verb agreement and infinitive structure are used.
