During an ethylene signalling pathway, what will have done  inside cytosol and nucleus . Given below some prediction about presence and absence of ethylene in column B match with column A

COLUMN A	COLUMN B
I-  In the presence of ethylene	a)  ETR1 signaling is repressed and CTR1 is inactive
II- In the absence of ethylene	b)  ETR1 activate CTR1, a Ser/Thr kinase
	c)  CTR1 phosphorylates the C-terminal domain of EIN2
	d)  The nonphosphorylated C terminus of EIN2 is cleaved by a protease
	e)  Phosphorylation of EIN2 inhibits proteolytic cleavage
	f)  EIN3 transcription factors are ubiquitinated and degraded in the nucleus by the 26S proteasome
	g)  EIN3 initiates a transcriptional cascade by activating expression of ethylene-responsive genes, including ERF1 transcription factor, leading to ethylene responses
