Select the polynomial that is a perfect square trinomial.

 9x2 + 9x + 1 36b2 − 24b + 8 16x2 + 24x + 9 4a2 − 10a + 25

To determine which polynomial is a perfect square trinomial, we need to identify which one fits the form \((ax + b)^2 = a^2x^2 + 2abx + b^2\).

Let's analyze each option:

1. \(9x^2 + 9x + 1\)
   - This does not fit the form of \((ax + b)^2\) because \(2ab \neq 9x\).

2. \(36b^2 - 24b + 8\)
   - This does not fit the form of \((ax + b)^2\) because the constant term does not match.

3. \(16x^2 + 24x + 9\)
   - This seems promising. Let's see if it can be written as \((4x + 3)^2\):
     \[
     (4x + 3)^2 = (4x)^2 + 2(4x)(3) + 3^2 = 16x^2 + 24x + 9
     \]
     This fits the form perfectly.

4. \(4a^2 - 10a + 25\)
   - This does not fit the form of \((ax + b)^2\) because \(2ab \neq -10a\).

Therefore, the polynomial that is a perfect square trinomial is:

\[
\boxed{16x^2 + 24x + 9}
\]
