To find the relative frequency of 7th graders who prefer dogs, you would divide the number of 7th graders who prefer dogs by the total number of students in 7th grade.

8 (7th graders who prefer dogs) / (36 (7th graders who prefer cats) + 8 (7th graders who prefer dogs) + 2 (7th graders with no preference)) = 8 / 46 = 0.1739

Converting this to a percentage gives you 17.4% rounded to the nearest tenth.

Therefore, the correct answer is:

A. 17.4%
