While researching a topic, a student has taken the following notes:
- The Mohs scale of mineral hardness is a ten-point scale that orders minerals by hardness based on their ability to scratch other minerals.
- Minerals with larger numbers are harder than minerals with smaller numbers and can leave visible scratches on them.
- Minerals with smaller numbers are softer than minerals with larger numbers and cannot leave visible scratches on them.
- The mineral fluorite has a Mohs scale number of 4.
- The mineral orthoclase has a Mohs scale number of 6.
- The mineral corundum has a Mohs scale number of 9.
The student wants to emphasize orthoclase's Mohs scale number. Which choice most effectively uses relevant information from the notes to accomplish this goal?
In the Mohs scale of mineral hardness, corundum (9) is ranked higher than fluorite (4).
A
Orthoclase has a Mohs scale number of 6, which means that it is harder than fluorite (4) but softer than corundum (9).
B
Orthoclase, fluorite, and corundum can be ordered by their ability to leave visible scratches on other minerals.
C
Corundum, which has a Mohs scale number of 9, can scratch both fluorite and orthoclase.
D
