Explanation:

Blood is a specialized connective tissue. It has different types of cells (like red blood cells, white blood cells, platelets) suspended in plasma. Bone marrow (first option) is where blood cells are made, not what blood itself is. Hemoglobin (a chemical compound, second option) gives blood its red color but is just a part of red blood cells. Muscle (third option) is a different tissue type. The fluid part (fourth option) is plasma, which is only one component of blood.

A specialized connective tissue composed of different types of cells suspended in plasma.
