What type of immunity is innate and does not involve memory?

• A. Adaptive immunity
• B. Acquired immunity
• C. Innate/nonspecific immunity
• D. Specific immunity

Answer: (C)

The correct answer is innate/nonspecific immunity because this type of immunity provides immediate, but short-term, defense against pathogens without the need for prior exposure to those pathogens. Innate immunity includes physical barriers such as skin and mucous membranes, as well as various immune cells like macrophages and neutrophils that respond quickly to a wide range of invaders. Unlike adaptive or acquired immunity, which develops a memory of specific pathogens and provides long-lasting protection, innate immunity does not improve with repeated exposures to the same pathogen. It acts as the first line of defense and is always present and ready to respond to infections.
