Answer:

A) 19×10^4, 5.72×10^3, 3.3×10^-1, 5.68×10^-3

Explanation:

The number that is not in scientific notation form is 19×10^4 = 1.9×10^5.

Ordering will be greatest to least when the different powers of 10 are in order greatest to least. In consideration of the above rewrite, the powers of 10 are ...

5, -3, 3, -1

When these are in the correct order, they would be 5, 3, -1, -3. This corresponds to the number ordering ...

19×10^4, 5.72×10^3, 3.3×10^-1, 5.68×10^-3 . . . . choice A

Additional comment

When the powers of 10 are the same, you need to compare the mantissas in the usual way.
