Direction: Which of the phrases a), b), c) and d) given below each statement should replace the phrase printed in bold in the sentence to make it grammatically correct ?
If the sentence is correct as it is given and 'No correction is required', mark e) as the answer.
Masses is plural, so it should be 'were' instead of 'was'. Also, the use of the word 'which' is incorrect. The correct word is 'who'. So, option d) is the correct answer.
