Directions: In the following question, four statements are provided. These statements form a coherent paragraph when properly arranged. Select the alternative representing the proper and logical sequencing of these statements.

A. There is a crucial difference between the perception of musical sounds and the perception of colors: the integration of musical sounds produces a new cognitive experience which is sensory - conceptual, i.e., the awareness of a melody, the integration of colors does not, it conveys nothing beyond the awareness of pleasant or unpleasant relationships.

B. Cognitively, the sensation of color qua color is of no significance because color serves an incomparably more important function: the sensation of color is the central element of the faculty of sight, it is one of the fundamental means of perceiving entities.

C. Visual harmony is a sensory experience and is determined primarily by physiological causes.

D. Color as such (and its physical causes) is not an entity, but an attribute of entities and cannot exist by itself.
