The answer is C.

Explanation:

You have to first turn the meter(s) into centimeters like the rest.
(They all MUST be the same type)
1m = 100cm

Now you have to simply the amounts.
Since we can divid all of the numbers by 4, we will simplify by 4.

100 / 4 = 25
12 / 3 = 4
4 / 4 = 1

Therefore your answer is C.

25, 4, 1
