In a relative frequency distribution, we calculate the percentage each interval contributes to the whole distribution. 
To convert a frequency distribution to relative percentages, we need to:

1. Add up all the frequencies to find the total
2. Divide each frequency by the total
3. Multiply each result by 100 to get the percentage

Using this method, we get the following percentages for the intervals:

- Interval 1: (2/10) x 100 = 20%
- Interval 2: (1/10) x 100 = 10%
- Interval 3: (1/10) x 100 = 10%
- Interval 4: (3/10) x 100 = 30%
- Interval 5: (3/10) x 100 = 30%

Therefore, the correct choice is C, which presents the corresponding percentages in each interval listed from top down: 20%,13%,17%,33%,17%.
