What response of cellular immunity would appear after complementary protein activation to keep pathogenic bacteria away from our body?

Notes: I do appreciate your explanation. Though I am facing multiple choices:

(a) wrapping the bacteria cell (b) immobilize the bacteria cell (c) destroying the bacteria cell by enzyme (d) creating pores on the bacteria cell

The key answer is (c) but then I do not know what enzymes make this happens. Any Idea?

As you can simply find on Wikipedia, the cellular immunity, or Cell-mediated immunity,

is an immune response that does not involve antibodies, but rather involves the activation of phagocytes, antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen.

The answer (c) (destroying the bacteria cell by enzyme) refers to the phagocytes, cells that contain many enzymes, like lysozymes. Those funny enzyme can destroy the bacteria cell's wall.

Actually, I think that the answer (d) could be right, but it's not complete. In fact not every enzymes works on the cell's wall!

After opsonization the antigen goes through phagocytosis or the complement system destroys it. The complement is a cascade of reactions, which at the end creates a hole (many holes) on the membrane of bacteria which causes lysis. http://en.wikipedia.org/wiki/Complement_membrane_attack_complex

So the right answer is d.) in your case.
