Explanation:

Only statements 2&3 are correct.

Recently, Jawaharlal Nehru Port became the first major port of the country to become a 100% Landlord port of India having all berths being operated on PPP model.

• In the landlord port model, the publicly governed port authority acts as a regulatory body and as landlord while private companies carry out port operations—mainly cargo-handling activities.
• Here, the port authority maintains ownership of the port while the infrastructure is leased to private firms that provide and maintain their own superstructure and install own equipment to handle cargo.
• In return, the landlord port gets a share of the revenue from the private entity.
• The role of the landlord port authority would be to carry out all public sector services and operations such as the award of bids for cargo terminals and dredging.

Hence option 2nd is correct.
