What does immunity provide in relation to disease?

Immunity provides resistance to disease by equipping the body with the ability to recognize, attack, and neutralize pathogens such as viruses and bacteria. When a person is immune to a disease, it means their immune system has developed a defense mechanism either through previous exposure to the pathogen or through vaccination. This resistance can manifest in various forms, such as the production of antibodies that specifically target and eliminate the pathogens or a rapid response from immune cells that recognize the invaders.

The other options do not accurately describe the primary role of immunity. Enhanced treatment options may be available for diseases but are not a direct consequence of immunity. Increased vulnerability to infections contradicts the concept of immunity, as immunity is focused on providing protection. Improved recovery time is indeed beneficial but does not encapsulate the fundamental purpose of immunity, which is to prevent disease rather than simply speed up recovery.
