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 filtration is effective for removing bacteria, fungi, and other larger microorganisms, standard sterilization filters typically have pore sizes that are too large to reliably remove viruses, which are much smaller than bacteria. Other options are generally not primary limitations of the process itself, or are less significant.
Hint
Think about the relative sizes of different microorganisms. What tiny infectious agents can pass through most filters?
