Spot the error in the following sentence. If no error say so.
For the last three days, I have been feeling out of sort. No error.
a b c d
Answer Options:

The correct answer is Option C (c).

Key Points:
• This question tests the knowledge of English idioms and fixed phrases, specifically in identifying errors within them.
• Option 3 is correct because the error lies in part 'c'. The correct idiomatic expression is 'out of sorts' (with an 's' at the end), not 'out of sort'. The phrase 'out of sorts' means feeling slightly unwell, unhappy, or slightly irritated. Because idioms are fixed expressions, their structural components cannot be altered.
• Parts 'a' and 'b' are grammatically correct. 'For the last three days' correctly sets a duration, and 'I have been feeling' correctly uses the present perfect continuous tense to indicate an action starting in the past and continuing to the present.
• MPSC error detection often relies on minor alterations to common idioms, prepositions, or fixed phrases.
• Key Takeaway: Remember: The correct idiom is 'out of sorts', meaning to feel mildly unwell or irritated.
