We are given the second derivative of a function \( f \) as:

\[
f''(x) = x^2(x - 2)^4(x - 3)^2
\]

We need to find the x-coordinates of the inflection points, which occur where \( f''(x) = 0 \) and the concavity changes.

### Step 1: Find where \( f''(x) = 0 \)
Set the second derivative equal to zero:

\[
x^2(x - 2)^4(x - 3)^2 = 0
\]

For this product to be zero, each factor must be zero:

- \( x^2 = 0 \) implies \( x = 0 \)
- \( (x - 2)^4 = 0 \) implies \( x = 2 \)
- \( (x - 3)^2 = 0 \) implies \( x = 3 \)

Thus, the critical points are \( x = 0 \), \( x = 2 \), and \( x = 3 \).

### Step 2: Check for concavity changes
For an inflection point to exist, the concavity must change at these critical points, i.e., \( f''(x) \) must change sign.

1. **At \( x = 0 \)**:
   - \( f''(x) = x^2 \) is always non-negative and doesn't change sign at \( x = 0 \). Therefore, \( x = 0 \) is **not** an inflection point.

2. **At \( x = 2 \)**:
   - \( (x - 2)^4 \) is always non-negative and doesn't change sign at \( x = 2 \). Therefore, \( x = 2 \) is **not** an inflection point.

3. **At \( x = 3 \)**:
   - \( (x - 3)^2 \) is also non-negative and doesn't change sign at \( x = 3 \). Therefore, \( x = 3 \) is **not** an inflection point.

### Conclusion:
None of the critical points lead to a change in concavity, so there are no inflection points.

Thus, the correct answer is **(A) none**.
