The choice of ticks as an example of a vector of biological agents is accurate because ticks are known carriers of pathogens that can cause various diseases in humans and animals. As arthropod vectors, they play a critical role in the transmission of biological agents, such as bacteria, viruses, and protozoa, through their bites. This means that they not only harbor these agents but also facilitate their spread from one host to another, making them significant in the context of public health and disease prevention.

In contrast, the other options do not serve as vectors in the same biological sense. Aircraft can transport biological agents over long distances but do not actively transmit pathogens themselves. Rivers can facilitate the spread of water-borne pathogens but are not vectors in the traditional biological sense. Health care facilities, while important in managing and preventing diseases, are places where diseases are treated rather than vectors of transmission.
