Explanation:

Only statements 1&4 are correct.

• Chandrayaan-3 has made history by becoming the first mission to soft-land on the lunar south pole, a region that has never been explored before.

• India now joins the United States, Russia, and China as one of the few countries to successfully land on the Moon.

• Chandrayaan-3's successful landing came after the setback of the Chandrayaan-2 mission's landing failure in 2019.

• Lessons from the Chandrayaan-2 mission were applied to Chandrayaan-3, focusing on a "failure-based" design approach to anticipate and mitigate potential issues. 

• Critical changes included strengthening the lander's legs, increasing fuel reserves, and enhancing landing site flexibility.

• Chandrayaan-3 is expected to operate for at least one lunar day (14 Earth days) on the lunar surface. 

• The Pragyan rover will move around the landing site within a radius of 500 meters, conducting experiments and sending data and images to the lander.

• The Vikram lander will relay the data and images to the orbiter, which will then transmit them to Earth.

• The propulsion module that carried the lander and rover configuration till 100 km lunar orbit also has a Spectro-polarimetry of Habitable Planet Earth (SHAPE) payload to study the spectral and Polari metric measurements of Earth from the lunar orbit. 

Hence option 2nd is correct.
