Explanation:

Step1: Recall unit abbreviations

• \(mm\) stands for millimeter (\(10^{- 3}\) meters).
• \(\mu m\) stands for micrometer (\(10^{-6}\) meters).
• \(nm\) stands for nanometer (\(10^{-9}\) meters).

Step2: Match with the value

• A red - blood cell's diameter of about eight micrometers. The abbreviation for micrometer is \(\mu m\).

Answer:

8\(\mu m\)
