Identify the incorrect word in the sentence from the options given below:

Ravi and Rohan replies promptly to the proposal put before them.

Replies

The correct answer is Option (4) → Replies

The incorrect word in the sentence is "replies". The correct sentence is "Ravi and Rohan replied promptly to the proposal put before them."

The word "replies" is in the present tense, while the rest of the sentence is in the past tense. This makes the sentence grammatically incorrect.

To correct the sentence, we need to change the verb "replies" to the past tense. The past tense of the verb "to reply" is "replied".

Therefore, the correct sentence is:

Ravi and Rohan replied promptly to the proposal put before them.
