Let's evaluate the given expression:

\[
(-3 + 10.5) \div (-1.5 + 3^2)
\]

**Step 1: Simplify each part inside the parentheses.**

1. Simplify \(-3 + 10.5\):
   \[
   -3 + 10.5 = 7.5
   \]

2. Simplify \(-1.5 + 3^2\):
   \[
   3^2 = 9
   \]
   So, \(-1.5 + 9\):
   \[
   -1.5 + 9 = 7.5
   \]

**Step 2: Divide the simplified results.**

\[
7.5 \div 7.5 = 1
\]

The answer is:

**B) 1**
