Let's evaluate the expression step by step. The expression is:

$\left[\frac{3^2}{2} - (1 + 4)\right] \div 0.5$

Step 1: Evaluate $3^2$

$3^2 = 9$

Step 2: Divide by 2

$\frac{9}{2} = 4.5$

Step 3: Add inside the parentheses

$1 + 4 = 5$

Step 4: Subtract from 4.5

$4.5 - 5 = -0.5$

Step 5: Divide by 0.5

$-0.5 \div 0.5 = -1$

The final answer is $-1$, which corresponds to option D.
