Attempt This Question
Not attemptedCorrect Answer: (d) They protect the body from the diseases caused by pathogens.
B-cells produce antibodies and T-cells kill infected cells or orchestrate immune responses; together they form the adaptive immune system that defends the body against pathogenic diseases. They do not mainly suppress immunity, relieve pain, or deal only with allergens, so options (a)–(c) are incorrect. ([niaid.nih.gov](https://www.niaid.nih.gov/research/immune-cells?utm_source=openai))
