Due to a genetic defect, an individual is unable to make T cytotoxic cells. Predict the most likely consequence. A. The individual will not be able to synthesize any antibodies. B. The individual will have SCID (severe combined immunodeficiency disease). C. The person will have frequent infections caused by Staphylococcus and Streptococcus. D. The person will not be able to adequately fight viral infections and infections caused by intracellular bacteria.

Cytotoxic T lymphocytes also known as CD8+ T cells are very important in defence of the immune system against intracellular pathogens, including viruses and bacteria and for tumour check. They recognize pathogens' antigen and then become activated killing infected or malignant cells.

Thus, a genetic defect in genes that encodes for its production will lead to the individual being not able to efficiently fight against these infections.

Answer:

The correct option is D:

"The person will not be able to adequately fight viral infections and infections caused by intracellular bacteria."

Explanation:

Cytotoxic T lymphocytes have an important role to play in the immune system, they belong to the category of cells that have the ability to kill off another cell. Cytotoxic T lymphocytes guards the host cell against attack of viruses and, in addition, also defends against possible (bacterial) infections that can be caused by harmful pathogens that multiply inside the cells of the host.

Hope that answers the question, have a great day!
