Read the sentence to find out whether there is any grammatical or idiomatic error in it. The error, if any, will be in one part of the sentence. The corresponding letter of that part is the answer. If the given sentence is correct as it is, then choose option ‘No Error’ as the answer response. (Ignore errors of punctuation, if any).

The government has (A)/ decided to give financial assistance (B)/ of ₹10,000 per month to all the (C)/ poor people overgoing organ transplant (D).

Correct option is D

Part (D) has a grammatical error where the word " undergoing" should be used instead of " overgoing" to make the sentence grammatically and contextually correct.
“Undergoing" means currently in the process of or receiving a particular treatment or procedure. In the sentence, the government is offering financial assistance to poor people who are in the process of undergoing an organ transplant procedure, so "undergoing" is the appropriate word choice to describe this situation.
The other parts of the sentence are grammatically correct.
Therefore, the correct sentence would be: "The government has decided to give financial assistance of ₹10,000 per month to all the poor people undergoing organ transplant.”
