Final answer:
Horizontal wood paneling makes a room seem wider by drawing the eye along the room's length.
Step-by-step explanation:
Horizontal wood paneling typically influences the perception of a room's width. When paneling is applied horizontally along the walls, it tends to draw the eye along the length of the room, making it seem wider than it actually is.
This is a design trick often used to enhance the spatial proportions of a room. Conversely, vertical paneling might make a room feel taller, as it draws the eyes upward. In this case, the correct answer to the question is that horizontal wood paneling makes it seem wider (C).
