Red blood cells are efficient oxygen transport cells. of the following characteristics, which is the major contributor to the significant oxygen-carrying capacity of a red blood cell?

The correct answer is - red blood cells are biconcave.

Explanation:

RBC or the red blood cells are the cells that play an important role by many means such as transferring nutrients, hormones, and oxygen throughout the body. The transfer of the oxygen is accompanied by the help of hemoglobin, a protein that carries oxygen and takes it to the different sites in the body.

These cells are biconcave which helps them to provide more cell surface area to grab or attain maximum space for hemoglobin which helpful in oxygen significant oxygen-carrying capacity of Red blood cells.

Thus, the correct answer - red blood cells are biconcave.
