Multiple Choice

Sterilizing filters have a pore size of 0.22 $\mu$ m.Which of the following statements is true?

• A)Bacterial cells are typically between 1,000-10,000 nm and pass through the filter, whereas most viruses are between 20 and 200 nm and are therefore blocked.
• B)Bacterial cells are typically between 1-10 \(\mu\)m and pass through the filter, whereas most viruses are between 20 and 200 nm and are therefore blocked.
• C)Bacterial cells are typically between 1-10 \(\mu\)m and are blocked by the filter, whereas most viruses are between 20 and 200 nm and therefore pass through.
• D)Bacterial cells are typically between 1-10 nm and are blocked by the filter, whereas most viruses are between 20 and 200 \(\mu\)m and therefore pass through.
