To convert a frequency distribution to relative percentages, we need to divide each frequency by the total number of observations and then multiply by 100 to get the percentage. The total number of observations can be obtained by adding up all the frequencies. For example, in the first interval (0-4), the frequency is 20. If the total number of observations is 100, then the relative percentage for this interval would be (20/100)*100 = 20%. Similarly, we can calculate the percentages for the other intervals and the result would be: 20%, 13%, 17%, 33%, and 17%. Therefore, the best choice is C.
