Step 1: Understanding Ceiling Designs.
A central design is typically the most appropriate for room ceilings. It focuses attention towards the centre of the room and creates a balanced, symmetrical look. Central designs can be intricate and often serve as a decorative focal point.
Step 2: Verifying the Options.
- Option (1): Corner designs are usually placed in the corners of the room, not on the ceiling's centre.
- Option (2): A central design works best for the ceiling as it directs attention to the middle and creates a symmetrical, balanced look.
- Option (3): Border designs are typically used for edges, not for the central portion of the ceiling.
- Option (4): "None of the above" is incorrect because the central design is the best option.
Conclusion:
Therefore, the correct answer is (2) Central design.
