D	None of the above

Explanation:

Detailed explanation-1: -Cleavage: mineral breaks along parallel, flat surfaces (cleavage planes). Example: Halite – three directions of cleavage, 90˚ to each other.

Detailed explanation-2: -Cleavage/Fracture: Halite has 3 planes of cleavage, perfect in three directions forming cubes. It’s fracture is conchoidal.

Detailed explanation-3: -Potassium feldspar – A nonmetallic mineral that is tan-to-pink, white, or green in color, has 2 perfect cleavage planes at 90° with no striations (a growth pattern that appears as thin grooves) on the cleavage surfaces, and has a hardness of 6.0.
