The correct answer is: a) High average annual rainfall.
Mawsynram is a village in the East Khasi Hills district of Meghalaya, India. It is considered one of the wettest places on Earth, with an average annual rainfall of 11,871 mm (467.4 in). The village is located in the Khasi Hills, which are known for their high rainfall. The monsoon rains are particularly heavy in Mawsynram, and the village receives an average of 108 inches of rain in July alone.
The high rainfall in Mawsynram is due to its location on the windward side of the Khasi Hills. The hills block the moisture-laden winds from the Bay of Bengal, which causes the rain to fall on the village. The high rainfall has made Mawsynram a popular tourist destination, and the village is known for its lush vegetation and beautiful scenery.
The other options are incorrect because:
- Mawsynram does not have any scenic waterfalls.
- Mawsynram does not have any unique cave formations.
- Mawsynram does not have any tea plantations.
