A certain cell type has existed in the blood and tissue of its vertebrate host's immune system for over 20 years.One day,it recognizes a newly arrived antigen and binds to it,subsequently triggering a secondary immune response in the body.Which of the following cell types most accurately describes this cell?

B)T cell
C)memory cell
D)secondary cell

Memory cells are immune cells that are generated after an initial immune response to an antigen. They remain in the body for a long time and can quickly recognize and respond to the same antigen if encountered again. In this scenario, the cell that recognizes the newly arrived antigen and triggers a secondary immune response is most likely a memory cell. B and T cells are both types of immune cells, but memory cells are a type of both B and T cells that have been activated during an immune response. "Secondary cell" is not a recognized term in immunology.
