It's not a specific blood type that brings oxygen close to cells, but rather a component of blood called red blood cells.

Here's why:

* Red blood cells contain a protein called hemoglobin. Hemoglobin binds to oxygen in the lungs and carries it throughout the body, delivering it to the cells that need it.

* Blood types (like A, B, AB, and O) are determined by different antigens present on the surface of red blood cells. These antigens are important for immune system function and blood transfusions, but they don't directly affect the oxygen-carrying capacity of the blood.

So, all blood types, regardless of their type, have red blood cells that carry oxygen to the cells.
