The correct Answer is:
To solve the question regarding the percentage of water that constitutes the total cellular mass, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Question**: The question asks for the percentage of water in the total cellular mass of a cell. 2. **Recall Cellular Composition**: We need to remember the average composition of a living cell. Water is a major component of cells. 3. **Identify Water Percentage**: It is known that water constitutes a significant portion of the cellular mass. Generally, water makes up about 70% to 90% of the total cellular mass. 4. **Analyze the Options**: - (a) 10% - Too low for water content. - (b) 30% - Still too low for water content. - (c) 50% - Approaching but still lower than the average. - (d) 90% - This is within the known range of 70-90%. 5. **Select the Correct Option**: Based on the information, the correct answer is (d) 90%. ### Final Answer: Water constitutes **90%** of the total cellular mass. Therefore, the correct option is **(d) 90**. ---
