Answer:
a) breaking of covalent bands.
Explanation:
The electron-hole pair enter the depletion region which has very high electric field. They undergo a tremendous acceleration. When these accelerated electrons collide with the atoms they can breakaway electrons from their bonds,Thus, creating additional electron/hole pairs and therefore, additional current. Now these secondary carriers are swept into the depletion region, they too are accelerated and the process repeats itself. Making an avalanche of current.
