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

Options

A. A
B. P
C. B
D. Z

Answer

To determine which letter is symmetrical about a vertical line, we will analyze each letter step by step.

### Step 1: Analyze the letter A
- Draw the letter A.
- Now, imagine or draw a vertical line down the middle of the letter A.
- Observe that the left side of the letter A is a mirror image of the right side when split by the vertical line.

**Conclusion for A**: The letter A is symmetrical about a vertical line.

### Step 2: Analyze the letter P
- Draw the letter P.
- Again, draw a vertical line down the middle of the letter P.
- Notice that the left side (the straight line) does not match the right side (the rounded part).

**Conclusion for P**: The letter P is not symmetrical about a vertical line.

### Step 3: Analyze the letter B
- Draw the letter B.
- Draw a vertical line down the middle of the letter B.
- Check the left side (the straight line) against the right side (the two rounded parts). They do not match.

**Conclusion for B**: The letter B is not symmetrical about a vertical line.

### Step 4: Analyze the letter Z
- Draw the letter Z.
- Draw a vertical line down the middle of the letter Z.
- Observe that the left side (the diagonal line) does not mirror the right side (the horizontal line).

**Conclusion for Z**: The letter Z is not symmetrical about a vertical line.

### Final Conclusion
After analyzing all the letters:
- The only letter that is symmetrical about a vertical line is **A**.

### Summary of the Answer
The correct answer is **A**.
