Question Detail
Question
What is the primary limitation of the filtration process for sterilization?
Correct Answer
Option D is the correct answer.
Detailed Explanation
While filters can effectively remove bacteria, fungi, and protozoa, standard sterilization filters typically have pore sizes that are too large to retain all viruses, making them generally unsuitable for complete viral removal for sterilization purposes.
Hint
Think about the relative sizes of different microorganisms and the physical mechanism of filtration.
