Choose correct answer for the below Statement.
Red Blood Cells (RBCs) are highly specialized for oxygen transport because
1. RBCs contain haemoglobin.
2. RBCs lack nucleus.
3. RBCs have many mitochondria.
4. RBCs can carry upto four oxygen molecules for each haemoglobin molecules.

Correct Answer: (B) 1, 2 and 4

Red Blood Cells (RBCs) are specialized for oxygen transport because they contain oxygen-binding haemoglobin, lack a nucleus (anucleated) to maximize internal space for haemoglobin, and each haemoglobin molecule can bind up to four oxygen molecules. Mitochondria are absent in RBCs to prevent them from consuming the oxygen they transport.
