Read each 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 alphabet corresponding to that part is your answer. If there is 'No error', the answer is ( e ). (Ignore errors of punctuation, if any.)
The blunder mistake (A)/ was the apparent failure of detectives (B)/ to inform the Parole Board that murderer (C)/ had threatened to return to kill her. (D)/ No Error (E)

Options

A. A
B. B
C. C
D. D

Answer

A

Explanation

The error lies in the irst part of the sentence where the usage of the words 'blunder' and 'mistake' together is superfluous as 'blunder' and 'mistake' together is superfluous as 'blunder' itself means 'a stupid or careless mistake'. Hence, option (a) will be the correct answer.
