Vedclass · Answer

(B) In the protoplasm of a living cell, water $(H_2O)$ is the most abundant constituent, accounting for approximately $70-90\%$ of the total weight. Since water consists of hydrogen and oxygen, and oxygen atoms are significantly heavier than hydrogen atoms, oxygen constitutes the highest percentage by mass among all elements in the protoplasm. Therefore, oxygen is the most abundant element by mass.
