Are rapidly being destroyed in the mountain regions that surround india.
a. rivers
c. forests
b. lakes
d. coal deposits

Hi, thank you for posting your question here at 

The answer would be forests, letter C. The clue in this question is in the "mountain regions". From here, you can eliminate lakes and coal deposits. Between rivers and forests, those that are "rapidly destroyed" would be the forests, since rivers become polluted, rather than destroyed,

c. forests

Explanation:

The forestlands are rapidly getting depleted as they support a variety of the species of median la tree as and the fruit trees the paper industry and the logging industry is using them for the commercial purpose and thus there preservation and protection is a matter of concern. The forest tracks of the lands are thus cleared and they are used of the settlements purpose and the resorts of all the sand thence they are declared for the domestication of cattle like the ranched and the grazing animals. hence the forest lands and is depleting at an alarming rate as this has now become a very fragile ecosystem.
