A

graphite has grreater affinity for oxygen

B

diamond has grreater affinity for oxygen

C

graphite is more stable than diamond

D

diamond is more stable than graphite

Text Solution

Verified by Experts

The correct Answer is:
D
The less the heat of combustion, the more stabe the compound. Obviously, as per the data given above.
