a. oxygen and nutrients
b. t cells
c. bone marrow
d. all of the above.

Explanation:

Blood's main functions include transporting oxygen (from the lungs) and nutrients (from digestion) to cells. T - cells are part of the immune system and not carried to every cell as a primary function like oxygen and nutrients. Bone marrow is in bones and not transported by blood to every cell. So, blood mainly carries oxygen and nutrients to every cell.

A. Oxygen and nutrients
