B
Key Concept
Epidemiological Triad vs. Tetrad
Explanation
The traditional epidemiological triad consists of three components: the host, the agent, and the environment. However, some models include a fourth component, the vector, forming an epidemiological tetrad. The statement is false because it incorrectly refers to the triad as including only host, agent, and environmental factors but labels it as a tetrad.
