Which of the following is defined as a disease which can be transmitted to humans from animals?

The term described in the question refers specifically to diseases that can be transmitted from animals to humans, which is precisely what a zoonotic disease is. Zoonotic diseases can be caused by various pathogens, including bacteria, viruses, parasites, and fungi, and they highlight the importance of understanding the connections between animal health and human health.

Systemic diseases affect multiple systems or organs within an animal but do not necessarily pertain to transmission between species. Contagious diseases refer to illnesses that can be spread from one individual to another within the same species, but this does not encompass the transference from animals to humans. Infectious diseases broadly cover diseases caused by infectious agents but lack the specific focus on the interspecies transmission that characterizes zoonotic diseases. Thus, the correct response accurately captures the specific nature of the disease transmission as outlined in the question.
