Explanation:

None of the above statements are correct.

NTPC Renewable Energy Ltd (NTPC-REL), a 100% subsidiary of NTPC, signed a MoU recently with Union Territory of Ladakh to set up the country’s first green Hydrogen Mobility based project in the region.

• Leh is soon to become India's first city to implement a green hydrogen  based mobility project with zero emission.
• NTPC REL has also received the go-ahead from Ministry of New and Renewable Energy (MNRE) to set up 4750 MW renewable energy park at Rann of Kutch in Khavada, Gujarat.
• This will be India’s largest solar park to be built by the largest power producer of the country.
• NTPC has recently revised its target of achieving 60GW renewables capacity by 2032, almost doubling the earlier target.

Recently, NTPC has commissioned India’s largest floating solar project of 10MW at Vishakhapatnam.

• India’s single largest solar park – Rann of Kutch
• India’s largest Floating Solar project – Visakhapatnam
• India’s first Green Hydrogen Mobility project – Ladakh

Hence option 4th is correct.
