When a mineral fractures along a cleavage plane,what does this suggest about the crystal structure of the mineral?
A)The atoms are arranged in a simple orderly arrangement with uniform bonding.
B)The crystal structure contains planes along which chemical bonding is much weaker than other directions.
C)The crystal grows only planar faces that become weak zones that form cleavage.
D)The crystal contains warped planes called twin planes that weaken the crystal structure and allow it fracture along a planar surface,causing cleavage.

Cleavage planes suggest that there are planes along which chemical bonding is much weaker than in other directions. This is due to the crystal structure containing planes of weak chemical bonds, allowing the mineral to fracture along a planar surface.
