In the context of infectious disease, which term refers to a microorganism that causes disease?

Explanation:
Pathogens are microorganisms that cause disease in a host, including bacteria, viruses, fungi, and parasites. This term is correct because it identifies the actual disease-causing agent. A symptom is a sign or feeling the patient experiences, not the cause. A vector is an organism that transmits a pathogen between hosts, aiding spread but not the organism that causes the disease. An antibiotic is a drug used to treat infections, not the disease-causing organism.
