The correct answer is Option 2: 3 only, which asserts that Pulicat Lake is spread over two states. This is correct as Pulicat Lake, the second largest brackish-water lake or lagoon in India, straddles the border of Andhra Pradesh and Tamil Nadu.

Statement 1: The Himalayas are not confined to five states in India. They span across several states in the north and northeastern parts of the country: Jammu & Kashmir, Himachal Pradesh, Uttarakhand, Sikkim, Arunachal Pradesh, as well as parts of Assam and West Bengal.

Statement 2: The Western Ghats also expand beyond five states. These mountain ranges stretch along the western edge of India’s Deccan Plateau and pass through the states of Gujarat, Maharashtra, Goa, Karnataka, Kerala, and Tamil Nadu.

In light of these explanations, all the options containing either statement 1 or 2 aren`t correct. Therefore, the correct answer is Option 2: 3 only.
