Answer :
The statement that pathogens are disease-causing agents found in the environment and can be passed from one individual to another best describes where pathogens are found. These include different types of microorganisms and can cause various infectious diseases. Therefore, the correct option is B.
The best description of where pathogens are found is: 'B. Pathogens are disease-causing agents that can be found in the environment and are passed from one individual to another.' Pathogens, including bacteria, viruses, fungi, and protozoa, are agents that cause disease by invading and multiplying in host tissues. They can spread infectious diseases through various transmission methods such as direct contact, airborne transmission, fecal-oral route, or by vectors. Medicine such as antibiotics can treat infections caused by bacteria, one type of pathogen, but it's crucial to remember that not all pathogens are bacteria, and antibiotics have no effect on viral infections.
