The question is incomplete as it does not have the options to which the provided options must be matched and the options are:

a. Includes cilia, mucous membranes, dendritic cells

b. Immunological response brought about by antibody production

c. Immunological response that kills infected host cells

d. Use(s) BCRs to recognize epitope. First step in clonal selection

e. Phagocytes that engulf anything foreign. Eventually display epitope to helper T cells using MHC I or II

f. Lymphocytes that activate B cells and CTLs

g. Differentiated B cells that are stored in lymph nodes to provide protection against future infections by the same pathogen

h. Produce and secrete antibodies

i. Kills infected host cells

a. Innate Immunity

b. Humoral Immunity

c. Cellular Immunity

d. Immature B cells

e. Dendritic cells

f. Th cells

g. Memory cells

h. Plasma cells

i. Cytotoxic T cells

Explanation:

a. Innate Immunity

- the immunity which is present from birth and provides immunity due to the presence of physical barriers like the production of mucus and the cilia.

b. Humoral Immunity

- the immunity which is provided by the immune cells present in the blood in which the main immune cells are the lymphocytes that produce antibodies

c. Cellular Immunity

- the immune response which provides immunity by killing the infected cell observed in the case of the virus-infected cell which is killed.

d. Immature B cells

- The immature B cell is the cell that matures into the plasma cell and the effector cell and is involved in the clonal selection

e. Dendritic cells

- the antigen-presenting cell which moves in the blood and tissues and when interact with an antigen kills the antigen and displays its part through MHC I and II.  

f. Th cells-

T helper cells are the T- lymphocytes that interact with the antigen and activates the B-lymphocyte activation and T cell activation pathway.

g. Memory cells

- the cells which are produced by when a pathogen interacts with the B lymphocytes and the B cells from the memory B cell for future recognition of the antigen

h. Plasma cells

- The cells on antigen interaction start producing the antibodies.

i. Cytotoxic T cells-

the T lymphocytes which are involved in cellular immunity.

Well, Saudi Arabia is known to be ruled by the Islamic law and is also known to not be a democracy (so options B and D are wrong).

Now, the head of the govenment is the king, and he is usually not  called "the supreme leader"... this is a term rather used in Iran.

So I think that the best answer is C. The royal family controls the government.(which is true!)
