Choosing people randomly from the telephone book is the best example of a representative sample because it includes individuals from a diverse range of backgrounds and demographics. This reduces the potential for bias and increases the generalizability of the results to the larger population. Option A is limited to students, option B is limited to those shopping in an expensive store, and option C is limited to churchgoers, which makes it less representative of the broader population.
