Answer 2

Answer:

The correct answer is Red blood cell (RBC)

Explanation:

• Red blood cells are also known as Erythrocytes. Red blood cells are the most abundant cell in blood. They are approximate $5$ million to $5.5$ millions of Red blood cells$/mm^{3}$.
• Red blood cell are devoid of nucleus which allows Red blood cells to carry more oxygen due to much more carrying capacity of Haemoglobin. ( As one molecule of Haemoglobin bind 4 molecule of oxygen.)
  
  Therefore , Guard cell , Epidermal cell and White blood cell contain nucleus where as RBC red blood cell is devoid of nucleus .
