Answer:
d. planes of weak bonding between certain layers of atoms
Step-by-step explanation:
Cleavage , is a type of planar feature of the rock , which develops due to the metamorphism and deformation .
It is a secondary type of rock foliation , i.e. , the separation between two rocks .
They are formed in fine grained rocks which is made from minerals , under high pressure .
The weak bonding between layers of atom , generates a cleavage .
