To answer this question, we need to understand the concept of Navratna and Maharatna PSUs in India.
Navratna PSUs are public sector undertakings (PSUs) that have been granted greater autonomy and financial powers by the Government of India. These companies have been given the authority to make investment decisions up to a certain limit without seeking government approval. As of April 2021, there are currently 16 Navratna PSUs in India.
Maharatna is a higher status granted to select Navratna PSUs. Maharatna PSUs have even greater financial powers and autonomy compared to Navratna PSUs. They have the authority to make investment decisions up to a higher limit without seeking government approval. As of April 2021, there are only 11 Maharatna PSUs in India.
Now, let's go through each option to understand which Navratna PSU has been awarded Maharatna status:
Option A) GAIL - This option is incorrect because GAIL (Gas Authority of India Limited) is a Navratna PSU but has not been awarded Maharatna status.
Option B) BHEL - This option is incorrect because BHEL (Bharat Heavy Electricals Limited) is a Navratna PSU but has not been awarded Maharatna status.
Option C) Coal India Ltd - This option is correct because Coal India Limited, which is a Navratna PSU, has been awarded Maharatna status.
Option D) HAL - This option is incorrect because HAL (Hindustan Aeronautics Limited) is a Navratna PSU but has not been awarded Maharatna status.
Therefore, the correct answer is Option C) Coal India Ltd. This option is correct because Coal India Limited has been awarded Maharatna status.
