Answer 1

Hint:
- It's situated on the West Ghat Mountain Pass between the Tamil Nadu Coimbatore and the Kerala Palakkad
- Vaigai Dam Constructed on one of the hills across the majestic Vaigai river.

Complete solution:
Hills like Andipatti, Elamalai, and Agathiya Malai can be found toward the south of Palghat Gap. While the Western Ghats is a constant gap, the distance in Palghat is 25 km.
 With a width of 24-30 kilometres (15-19 mi), it has an average elevation of 140 metres (460 ft). The pass is situated to the north between the Nilgiri Hills and south between the Anaimalai Hills.

Now lets see the options :

a. Palghat gap : Hills like Andipatti, Elamalai, and Agathiya Malai can be found toward the south of Palghat Gap. While the Western Ghats is a constant gap, the distance in Palghat is 25 km. Thus this is the right option.
b. Varshanadu hills : Varusanadu is a panchayat village in Tamil Nadu's Theni district, which is situated on the bank of the Vaigai River. The other known hills in this region/ valley are Panchanathan hills and Velli Malai. Thus this is the wrong choice.
c. Thekkady hills : Thekkady is situated close to the border between Kerala and Tamil Nadu. This place is famous for the Wildlife Sanctuary of Periyar.thus this option is wrong too.
d. None of the above : option A which is palghat gap is right answer thus this option is wrong too.

Hence, the correct answer is option A.

Note:
- The landslide due to rivers flowing in opposite directions triggered the palghat gap.
- Tamil Brahmins migrated to Palakkad from Central Tamil Nadu through the Palakkad Gap from the 15th century to the 18th century.
- The name Anamala comes from the word Anai or Ana, i.e. Elephant and Malay and Malay or Mala meaning hill, i.e. Elephant hill.
