Resistance to disease is known as immunity. Infection (option A) refers to the process of harmful microorganisms entering and multiplying in an organism's body. Parasite (option C) refers to an organism that lives on or in another organism and depends on it for its survival. Fungus (option D) refers to a group of eukaryotic organisms that typically reproduce via spores and can cause disease in certain conditions, but it is not the general term for resistance to disease. Therefore, the term immunity (option B) is the most appropriate and accurate choice for the given question.
