    \nThe correct answer is B) 1-3-4-2.
    \n<\/section>\n
    \n– The hardness of minerals is commonly measured using the Mohs Hardness Scale, which ranks minerals from 1 (softest) to 10 (hardest) based on their ability to scratch one another.
    \n– The Mohs scale values for the given substances are:
    \n– Gypsum: Mohs Hardness = 2
    \n– Topaz: Mohs Hardness = 8
    \n– Fluorite: Mohs Hardness = 4
    \n– Feldspar (usually Orthoclase): Mohs Hardness = 6
    \n– Arranging these substances in order of increasing hardness (from softest to hardest):
    \n1. Gypsum (2)
    \n2. Fluorite (4)
    \n3. Feldspar (6)
    \n4. Topaz (8)
    \n– The correct order using the list numbers is 1-3-4-2.
    \n<\/section>\n
    \nThe full Mohs scale is: 1. Talc, 2. Gypsum, 3. Calcite, 4. Fluorite, 5. Apatite, 6. Feldspar, 7. Quartz, 8. Topaz, 9. Corundum, 10. Diamond. Each mineral on the scale can scratch the ones below it. For example, Fluorite (4) can scratch Gypsum (2) and Calcite (3), but cannot scratch Apatite (5) or Feldspar (6).
