Quizplus · Accepted Answer

The phenomenon described is the moon illusion, and it is caused by a reduction in the size constancy effect. Choice A is incorrect because while the phenomenon is commonly known as the lunar illusion, the term "lunar" specifically refers to the moon itself rather than the illusion. Choice B is incorrect because size constancy cues are not the cause of the phenomenon, but rather their reduction is what creates the illusion. Choice D is incorrect because while size constancy cues are involved in the illusion, it is specifically referred to as the moon illusion rather than the lunar illusion.
