# Given the Assertion and Reason below, Choose one of the following responses $\begin{array}{1 1}\text{Assertion:The pigment cytochrome controls photomorphogenetic responses.}\\\text{Reason:Cytochrome pigment occurs in two photoreversible forms.}\end{array}$

$\begin{array}{1 1}(A)\;\text{Both assertion and reason are true and the reason is a correct explanation of the assertion}\\(B)\;\text{Both assertion and reason are true but reason is not a correct explanation of the assertion}\\(C)\;\text{Assertion is true but the reason is false}\\(D)\;\text{Both assertion and reason are false}\end{array}$
