Correct option is A
The segment that contains an error in the given sentence is
(a) Neetu have been.
· The correct sentence should be: "Neetu has been waiting for me since 10 o'clock in the morning."
· In this sentence, the
subject is "Neetu," which is
singular.
· Therefore, the
verb should also be singular, which is "has been" instead of "have been."
· The correct form of the verb to use with a singular subject is "has been."
· The other segments of the sentence are correct.
