Explanation:

Both statements are correct.

• The Sudarshan Setu is also known as the Okha-Beyt Dwarka Signature Bridge. 

• It is India's longest cable-stayed bridge connecting the Okha mainland and the Beyt Dwarka island in Gujarat. 

• The bridge is technically a sea link, a first for Gujarat, with a total length of 4,772 meters, featuring a 900-meter-long cable-stayed section.

• It also has solar panels installed on the upper portions of the footpath, generating one megawatt of electricity.

Hence option 3rd is correct.
