First, let's round each number to the nearest 10:

- 124 rounds to 120
- 38 rounds to 40
- 71 rounds to 70
- 207 rounds to 210

Now, let's add these rounded numbers together:

120 + 40 + 70 + 210 = 440

So, an estimate of the expression 124 + 38 +71 + 207, when each value is rounded to the nearest 10, is 440. Therefore, the answer is C. 440.
