Options

A. Mountain
B. Bread
C. Room
D. Kite

Answer

To determine which of the following options is not a 3-D figure, we need to analyze each option based on the characteristics of three-dimensional shapes. A 3-D figure has length, width, and height.

**Step 1: Analyze the options**
- **Mountain**: A mountain has height, width, and length. Therefore, it is a 3-D figure.
- **Braid**: A braid has length, width, and height. Thus, it is also a 3-D figure.
- **Room**: A room has height, width, and length. Hence, it qualifies as a 3-D figure.
- **Kite**: A kite has length and width, but it does not have a height. Therefore, it is not a 3-D figure.

**Step 2: Conclusion**
Based on the analysis, the option that is not a 3-D figure is the **kite**.
