- Graphite
- Fullerene
- Diamond
- Carbon black
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
- Diamond is the hardest naturally occurring substance, and its hardness makes it an ideal material for use as an abrasive in sharpening hard tools. Hence, the correct answer is (3).
- Graphite is soft and used as a lubricant, not as an abrasive, so option (1) is incorrect.
- Fullerene is a molecular form of carbon and is not used as an abrasive, making option (2) incorrect.
- Carbon black is primarily used in rubber and ink production, not for sharpening tools, so option (4) is incorrect.
- Graphite is soft and used as a lubricant, not as an abrasive, so option (1) is incorrect.
- Fullerene is a molecular form of carbon and is not used as an abrasive, making option (2) incorrect.
- Carbon black is primarily used in rubber and ink production, not for sharpening tools, so option (4) is incorrect.
