Henry: Some scientists explain the dance of honeybees as the means by which honeybees communicate the location of whatever food source they have just visited to other members of the hive. But honeybees do not need so complicated a mechanism to communicate that information. Forager honeybees returning to their hive simply leave a scent trail from the food source they have just visited. There must be some other explanation for the honeybees' dance.

Winifred: Not necessarily. Most animals have several ways of accomplishing critical tasks. Bees of some species can navigate using either the position of the Sun or the memory of landmarks. Similarly, for honeybees, scent trails are a supplementary not an exclusive means of communicating.

The point at issue between Henry and Winifred is whether

(A) theories of animal behavior can be established on the basis of evidence about only one species of animal
(B) there is more than one valid explanation for the dance of honeybees
(C) honeybees communicate the location of food sources through their dance
(D) the honeybee is the only species of bee that is capable of communicating navigational information to other hive members
(E) the honeybee's sense of smell plays a role in its foraging strategies

I got this wrong and am still trying to convince myself with the OA...

C it is.

Henry says --> Scientists explain honeybees dance as the means of communicating location. But why would honeybees use such complicating mechanism for communication. Forager honeybees communicate to other members by leaving a scent trail. Surely there is some other explanation for why honeybees dance.

Winifred says --> Most animals use several ways for a task. For example. Bees can navigate using either sun position or memory of landmark. Similarly, for honeybees, scent trails are a supplementary means of communicating (which means the other means of communicating is honeybees dance)

So the point at issue is whether honeybees communicate the location of food sources through their dance

I was choosing between B and C. Could you explain why B is wrong?
Henry argues that "There must be some other explanation for the honeybees' dance" and Winifrid disagrees with him...so I thought B was right...

Can someone explain why the answer choice is C?
