• A. 2:3
• B. 1:5
• C. 1:4
• D. 2:5

Hint:

Greek Proportions in Design: Golden Mean ratios are $2:3, 3:5, 5:8$. Avoid equal splits ($1:1$) or extreme disproportion ($1:5$).

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Design principles in interior architecture utilize classic Greek proportions and the Golden Mean ratio for aesthetically pleasing spatial division.
Key Formula or Approach:
\[ \text{Golden Section / Greek Ratios} = 2:3, \quad 3:5, \quad 5:8 \quad \left( \approx 1 : 1.618 \right) \]

Step 2: Detailed Explanation:
In architectural design and interior decoration:
The ancient Greek law of proportion (the Golden Oblong Golden Section) states that relationships of pleasing aesthetic proportion are based on ratios where the smaller dimension is to the larger dimension as the larger is to the sum (such as 2:3, 3:5, 5:8, 8:13).
The ratio 2:3 is standardly used for dividing wall spaces, arranging furniture groupings, and creating balanced rectangular room divisions.

Step 3: Final Answer:
Therefore, the ideal Greek proportion is 2:3, corresponding to option (A).
