A relative class frequency is defined as the proportion of all observations that falls into a given class in a frequency distribution. Option A describes the actual number of observations in a given class, while option C describes the width of a class interval. Option D specifies the number of observations in the smallest class only, which is not representative of the entire frequency distribution. Therefore, the correct choice is B.
