In the question below, four sentences have been given. Out of four sentences, one sentence is error-free. Find out which of the following sentence is error-free. If all the given sentences have errors, then choose option ‘None is correct’ as the answer choice.

Correct option is E

Correct answer: option e. None is correct
Let us now evaluate each sentence with detailed grammatical analysis, identify the specific error, and also provide a correct version with example.
(a) Despite of being late, he managed to catch the train that left five minutes earlier than usual.
Error: Incorrect use of "Despite of".
· The word “despite” is a preposition and should not be followed by “of”.
· The correct usage is either “despite” or “in spite of”, not both together.
Correct version:
Despite being late, he managed to catch the train that left five minutes earlier than usual.
Example: Despite having a headache, she continued working.
(b) The committee have decided to postpone the event due to insufficient participation from the members.
Error: Subject-verb agreement.
· The noun “committee” is a collective noun and is treated as singular when acting as a single unit.
· Hence, it should be “has” decided, not “have”.
Correct version:
The committee has decided to postpone the event due to insufficient participation from the members.
Example: The team has reached a unanimous decision.
(c) She not only completed the project on time but also managing the team efficiently during the crisis.
Error: Parallelism in verb forms.
· The sentence uses “not only … but also”, which requires both parts to be grammatically parallel.
· “completed” is past tense, so the second verb must also be in past tense: “managed”, not “managing”.
Correct version:
She not only completed the project on time but also managed the team efficiently during the crisis.
Example: He not only wrote the proposal but also presented it successfully.
(d) Each of the documents require verification before they are sent for final approval by the manager.
Error: Subject-verb agreement.
· “Each” is always singular, even if followed by a plural noun like “documents”.
· Therefore, it must be: requires, not “require”.
Correct version:
Each of the documents requires verification before they are sent for final approval by the manager.
Example: Each of the students deserves recognition for their efforts.
(e) None is correct.
This is the correct option, because all four sentences above contain grammatical errors, and therefore, no sentence is error-free.
Conclusion:
Every option from a to d contains a clear grammar or structure error. Thus, option e. None is correct is the right answer.
