Which of the following letters is symmetrical about a horizontal line?

Options

A. A
B. C
C. Y
D. Z

Answer

To determine which of the given letters is symmetrical about a horizontal line, we will analyze each letter one by one.

### Step-by-Step Solution:

1. **Analyze Letter A:**
- Draw a horizontal line through the middle of the letter A.
- Observe the shape above and below the line.
- The top of A is closed (the triangle part), while the bottom is open (the legs of A).
- **Conclusion:** There is no symmetry; therefore, option 1 (A) is rejected.

2. **Analyze Letter C:**
- Draw a horizontal line through the middle of the letter C.
- Observe the shape above and below the line.
- Both the top and bottom of C appear as a similar arc.
- **Conclusion:** There is symmetry; therefore, option 2 (C) is the correct answer.

3. **Analyze Letter Y:**
- Draw a horizontal line through the middle of the letter Y.
- Observe the shape above and below the line.
- The top part of Y has two arms, while the bottom part has a single line.
- **Conclusion:** There is no symmetry; therefore, option 3 (Y) is rejected.

4. **Analyze Letter Z:**
- Draw a horizontal line through the middle of the letter Z.
- Observe the shape above and below the line.
- The top and bottom parts of Z are different (the top is diagonal while the bottom is horizontal).
- **Conclusion:** There is no symmetry; therefore, option 4 (Z) is rejected.

### Final Answer:
The letter that is symmetrical about a horizontal line is **option 2 (C)**.
