The correct answer is: b) Khasi Hills.
Shillong Peak is the highest peak in Meghalaya, India. It is located in the Khasi Hills, which are a mountain range in the northeastern part of the country. The Khasi Hills are known for their beautiful scenery and their unique culture. The people of the Khasi Hills are known for their matrilineal society, in which property and inheritance are passed down through the female line.
The other options are incorrect because they are not the location of Shillong Peak. The Garo Hills are located to the west of the Khasi Hills, the Jaintia Hills are located to the east of the Khasi Hills, and the Mikir Hills are located to the north of the Khasi Hills.
