(I)CAP or CRP
(II)long terminal repeats (LTRs)
(III)riboswitches
(IV)SWI/SNF

C)I,III
D)II,IV
E)III,IV

CAP or CRP, LTRs, and riboswitches are all effective at controlling gene expression relative to the concentration of a metabolite or catabolite. SWI/SNF, on the other hand, is a chromatin remodeling complex and is not directly involved in controlling gene expression in response to metabolite or catabolite concentrations. Therefore, the correct choice is C, which includes the three options that are relevant for this question.
