Complement proteins are a group of proteins that play a key role in the immune system. These proteins form the membrane attack complex (MAC), which creates pores in the membranes of pathogens, leading to their destruction.
Cytokines are signaling molecules that mediate and regulate immunity, inflammation, and hematopoiesis, but they do not form the membrane attack complex.
Interferons are signaling proteins produced by host cells in response to the presence of viruses, bacteria, and other pathogens, but they do not form the membrane attack complex.
Interleukins are a group of cytokines that play key roles in immune responses, but like interferons and cytokines, they do not form the membrane attack complex.
Conclusion: The correct answer is Option D: Complement proteins.
