Answer :
The correct answer to the question is:
c. Talc is the softest mineral and diamond is the hardest mineral
Explanation:
1. The Mohs hardness scale is a scale used to measure the hardness of minerals, ranging from 1 (softest) to 10 (hardest).
2. Talc has a hardness of 1 on the Mohs scale, making it the softest mineral. It can be easily scratched by other minerals.
3. Diamond has a hardness of 10 on the Mohs scale, making it the hardest mineral. Diamond is extremely hard and can scratch all other minerals.
Therefore, option c is correct because talc is the softest mineral with a hardness of 1, and diamond is the hardest mineral with a hardness of 10 on the Mohs hardness scale.
