- A.
  
  10 : 2

Explanation
The ratio 10:2 is equal to 100:20 because both ratios can be simplified to 5:1. This means that for every 5 units in the first term of the ratio, there is 1 unit in the second term. So, if there are 100 units in the first term, there will be 20 units in the second term, resulting in the ratio 100:20.
