Model of cry1 interactions with COP1/SPA1 in the regulation of photomorphogenesis, what will happen in the dark as well as in the light in wild type condition of cryptochrome?

a) In the dark, COP1/SPA1 acts to degrade transcription factors such as HY5, which is required for photomorphogenesis

b) In the dark, cry1 is activated by phosphorylation and forms a complex with COP1 and SPA1 via the C-terminal domain, preventing them from degrading protein HY5

c) In the light, COP1/SPA1 acts to degrade transcription factors such as HY5, which is required for photomorphogenesis

d) In the light, cry1 is activated directly by blue light and indirectly by blue light induced phosphorylation and forms a complex with COP1 and SPA1 via the C-terminal domain, preventing them from degrading protein HY5

e) In light as well as in dark both case cryptochrome perfom same function such as forming a complex with COP1/ SPA1 thereby promoting an increase in HY5 protein levels and transcription
