D. `0.0929`

Answer

To find the sum of the decimals \(0.0457\) and \(0.0072\), follow these steps:

### Step 1: Align the Numbers
Write the numbers one below the other, ensuring that the decimal points are aligned:

```
0.0457
+ 0.0072
```

### Step 2: Add the Numbers
Start adding from the rightmost digit (thousandths place) to the left:

1. **Thousandths place**: \(7 + 2 = 9\)
2. **Hundredths place**: \(5 + 7 = 12\) (write down 2 and carry over 1)
3. **Tenths place**: \(4 + 0 + 1 (carry) = 5\)
4. **Units place**: \(0 + 0 = 0\)

Now, write the result below the line:

```
0.0457
+ 0.0072
--------
0.0529
```

### Final Answer
The sum of \(0.0457\) and \(0.0072\) is \(0.0529\).
