Match the following column given fluence with its induce phytochrome responses;

COLUMN A	COLUMN B
A) low-fluence responses (LFRs)	i) do not show Photoreversibility while Law of Reciprocity is followed
B)  high irradiance responses (HIRs)	ii) Shows the Photoreversibility and also the Law of Reciprocity is followed
C) Very low fluence response (VLFR)	iii) It will absorb red and blue light and responses is measuredly recepted by phytochrome A
	iv) In dark-grown: far red, blue, UV-A recepted by Photoreceptor phyA and cryptochrome
	v) ) It will absorb Red, far-red and responses is measurely recepted by phyB, phyD, phyE
