Correct option is A
Explanation:
The error is in
option (a) – "a IPS officer".
Grammatical Rule – Use of Articles (a/an):
· Use
“a” before words that start with a
consonant sound.
· Examples: a doctor, a teacher, a house.
· Use
“an” before words that start with a
vowel sound.
· Examples: an engineer, an umbrella, an honest man.
In the phrase “a IPS officer”, the acronym “IPS” begins with the letter “I”, which is pronounced
/aɪ/ — a vowel sound. Therefore, the correct article is
“an”, not “a”.
