Arun has prepared `0.01%` (by mass) solution of sodium chloride in water. Which of the following correctly represents the composition of the solutions?
(a) 1.00 g of NaCl + 100 g of water
(b) 0.11 g of NaCl + 100 g water
(c) 0.01 g of NaCl + 99.99 g of water
(d) 0.10 g of NaCl + 99.90 g of water

Explanation

To solve the problem, we need to determine which option correctly represents a `0.01%` (by mass) solution of sodium chloride (NaCl) in water. We will use the formula for mass percentage to evaluate each option.

### Step-by-Step Solution:

1. **Understand the formula for mass percentage**:
The mass percentage of a solution is given by the formula:
\[
\text{Mass Percentage} = \left(\frac{\text{Mass of Solute}}{\text{Mass of Solute} + \text{Mass of Solvent}}\right) \times 100
