Answer
This option is correct. Both T cells and B cells possess immunological memory, allowing them to remember previously encountered pathogens and mount a faster and more effective immune response upon re-exposure.

Answer
This option is incorrect. While T cells and B cells can respond to pathogens, their primary response is slower during first exposure compared to the secondary response.
Step 3

Answer
This option is incorrect. T cells and B cells do not act as physical barriers; they function as part of the adaptive immune response.

Answer
This option is incorrect. While B cells can produce antibodies that bind to viruses and bacteria, T cells specifically recognize infected cells, rather than attaching to pathogens directly.
