A study of guppy fish shows that a male guppy will alter its courting patterns in response to feedback from a female guppy. Males with more orange on one side than the other were free to vary which side they showed to a female. Females were drawn to those males with more orange showing, and males tended to show the females their more orange side when courting.

Which one of the following, if true, provides the most support for the argument?

(A) When a model of a female guppy was substituted for the female guppy, male guppies still courted, but were not more likely to show their side with more orange.
(B) In many other species females show a preference for symmetry of coloring rather than quantity of coloring.
(C) No studies have been done on whether male guppies with more orange coloring father more offspring than those with less orange coloring.
(D) Female guppies have little if any orange coloring on their sides.
(E) The male and female guppies were kept in separate tanks so they could see each other but not otherwise directly interact.

supports the arguments. The model will not show any interest so the male guppies will not be more interested to show their orange color.

(B) In many other species females show a preference for symmetry of coloring rather than quantity of coloring.
not related to argument

(C) No studies have been done on whether male guppies with more orange coloring father more offspring than those with less orange coloring.
argument is related to courting only. no of offspring may depend on other factors also.

(D) Female guppies have little if any orange coloring on their sides.
not related to argument.

(E) The male and female guppies were kept in separate tanks so they could see each other but not otherwise directly interact.
argument says that male guppies vary their courting behavior as per female guppies response. so above statement has no effect.

Give Kudos if helpful!!!!!
