Given below are four sentences, out of which one sentence is grammatically correct. Choose the option which points out the grammatically correct sentence. If all sentences are incorrect. Choose ‘All sentences are incorrect’ as your answer.

Correct option is E

The correct answer is (E) All sentences are incorrect.

Here is the breakdown of the errors in each sentence:

• Sentence (A) Error: In the "Not only... but also" construction, the verb must agree with the closest subject. Since "teachers" is plural, the verb should be "were" instead of "was."
• Sentence (B) Error: As discussed in previous examples, "Despite" is never followed by "of." It should be "Despite the high cost..." or "In spite of the high cost..."
• Sentence (C) Error: This sentence uses the Past Perfect tense ("had"). The past participle of "hide" is "hidden," not "hid." It should read: "...the culprit had hidden the stolen jewelry."
• Sentence (D) Error: Similar to sentence (A), when using "Neither... nor," the verb agrees with the nearest subject. Since "employees" is plural, the verb should be "are" instead of "is."
