Options
A Spherical with a nucleus
B Biconcave disc with a long axis of approximately 8 µm and thickness of 2 µm
Correct Answer
C Biconcave disc with a long axis of 2 µm and thickness of 8 µm
D Flat oval with a visible nucleus
Correct Answer

Option B is the correct answer.

Detailed Explanation

A normal, unstressed human red blood cell is a biconcave disc with a long axis of approximately 8 µm and a thickness of 2 µm. This unique shape maximizes surface area for gas exchange and allows flexibility to pass through narrow capillaries.

Hint

This shape is concave on both sides and has dimensions roughly 8 by 2 micrometers.
