Electron-hole pairs are generated in ___________

a) Depletion region 
b) Diffusion region 
c) Depletion region 
d) P-type region

Answer : - Depletion region

Photons are absorbed in both depletion and diffusion regions. The position and width of absorption region depends on incident photons energy. The absorption region may extend throughout device in weakly absorption of photons. Thus carriers are generated in both regions.
