Question

What is the primary limitation of the filtration process for sterilization?
Options
A It leaves toxic residues in the filtered material
B It cannot remove all bacteria
C It is too slow for practical use
D The pores are not small enough to filter out viruses
Correct Answer
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.
