Explanation:

- Option 1: REC Limited

- In September 2022, REC Limited was granted the 'Maharatna' status by the Indian government. This status provides a greater degree of financial and operational autonomy to public sector enterprises.

- Option 2: Coal India Limited

- Coal India Limited has held 'Maharatna' status since 2011. It was not newly awarded this status in 2022.

- Option 3: Indian Oil Corporation Limited

- Indian Oil Corporation Limited has also been a 'Maharatna' company since 2011, long before 2022.

- Option 4: NTPC Ltd.

- NTPC has had 'Maharatna' status since 2010, so it wasn't a new addition in 2022.

- Option 5: None of the above

- This is incorrect because REC Limited was awarded the status.
