Answer 1

The correct answer is "insect." In the context of diseases, a vector is an organism that transmits pathogens from one host to another. Insects, such as mosquitoes or ticks, often serve as vectors for diseases like malaria or Lyme disease. While bacteria, parasites, and viruses can cause diseases, they are not considered vectors themselves.
