Toads in a particular population vary in size. A scientist observes that in this population, large males mate with females significantly more often than small males do. All the following are plausible hypotheses to explain this observation EXCEPT
(A) Females select large males more often than they select small males as mates.
(B) Small females are more likely to mate with small males and large females are more likely to mate with large males.
(C) Large males are successful in competing for mates more often than small males are.
(D) Large males occupy more breeding territory than small males do.
(E) The calls produced by large males are more attractive to females than the calls made by small males.
