Answer
A is False and R is True.
Reason — Disease-causing germs are called pathogens (e.g., bacteria, viruses). Vectors are organisms (usually insects) that transmit pathogens from one host to another.
Vectors like mosquitoes, houseflies, and ticks help in spreading pathogens. Example: Anopheles mosquito transmits Plasmodium (causes malaria).
