Best approach to this question would be through an example and for easy calculations, let us assume the number we are dividing to be 3I. Divide the incorrect product by 100
II. Multiply the incorrect product by 0.01
III. Divide the incorrect product by 0.01
A. I only
B. II only
C. III only
D. I and II only

So originally: 3/0.0003 = 3/3*10^-4 = 10^4 (This should have been the actual result)
But erroneous result: 3/0.03 = 3/1*10^-2 = 10^2 (This is what we got)
So we need to arrive at 10^4 from 10^2, so let us look at the possible options given to us to see what gets us to the desired result and what does not
I. Divide the incorrect product by 100
10^2/100 = 1 which is not our desired result so NO
II. Multiply the incorrect product by 0.01
10^2 * 0.01 = 1 which is not our desired result so NO
III. Divide the incorrect product by 0.01
10^2/0.01 = 10^4 which is our desired result so YES
Answer - III only => C

0.03 is larger than 0.0003, so we meant to divide our original number into smaller pieces than what we ended up putting into the calculator. If we meant to have smaller pieces, we should have had more of them.
I. Would give us fewer pieces, not more. I is wrong. A, D, and E are out.
II. Would give us fewer pieces, not more. II is wrong. B is out.
Answer choice C.
