Explanation:

- Option 1: CMC Limited

CMC Limited was fully privatised. The government sold its entire stake to Tata Consultancy Services (TCS) in 2014, making it 100 percent privately owned.

- Option 2: Maruti Udyog Limited

The Indian government divested its stake in Maruti Udyog Limited to Suzuki, making it a private company.

- Option 3: Centaur Hotel

The government sold Centaur Hotel properties, but not the entire company. Some hotels were sold to private players, but not 100 percent privatisation of the whole company.

- Option 4: VSNL (Videsh Sanchar Nigam Limited)

The government sold a controlling stake to Tata Group, but initially retained some shares and sold the rest later.

Option 1: CMC Limited is the correct answer.
