Task: Class Definition Understanding (ontology: Sciences/Biology)

Which of the following definitions best describes 'alpha-beta T cell differentiation involved in immune response'?

A. The process in which an antigenically naive CD8-positive, alpha-beta T cell acquires the specialized features of an effector, regulatory, or memory T cell as part of an immune response. Effector T cells include cells which provide T cell help or exhibit cytotoxicity towards other cells.
B. The expansion of an alpha-beta T cell population by cell division as part of an immune response.
C. The process in which an antigenically naive alpha-beta T cell acquires the specialized features of an effector, regulatory, or memory T cell during an immune response. Effector T cells include cells which provide T cell help or exhibit cytotoxicity towards other cells.
D. The process in which a relatively unspecialized T cell acquires specialized features of a mature CD4-positive, alpha-beta T cell.

Answer: The process in which an antigenically naive alpha-beta T cell acquires the specialized features of an effector, regulatory, or memory T cell during an immune response. Effector T cells include cells which provide T cell help or exhibit cytotoxicity towards other cells.
