D)I, II

E)I, III, IV - Correct Option ((Kinase cascade refers to series of protein kinases that activates one another in sequence, leading to the amplification of the signal. Cell signals can be self-regulating for example Ras can inactivate itself through self-regulation by iintrinsic GTPase activity. Also, Multiple intracellular processes can be initiated simultaneously through signal cascade)
