Correct option is D
Sol. Asepsis refers to the complete absence of pathogenic microorganisms. It is a fundamental principle in infection control to ensure sterile conditions during medical or surgical procedures.
Explanation of each option: • (a) The removal of all foreign material – This is cleaning or decontamination, not asepsis itself. It’s a part of achieving aseptic conditions. • (b) The presence of pathogens – Opposite of asepsis. Presence of microbes indicates contamination or infection. • (c) The act of soiling or contamination – Contamination violates asepsis, making this option incorrect. • (d) The absence of pathogens – Correct. Asepsis means keeping an area or procedure free from harmful microorganisms to prevent infection.
