The given expression is:

$(3 - 2^2) + 5$

First, simplify the expression inside the parentheses:

$2^2 = 4$

Thus, the expression becomes:

$(3 - 4) + 5 = -1 + 5$

Now simplify:

$-1 + 5 = 4$

We need to find which expression is equivalent to 4. Let's check the options:

1. $3^2 - 5$: $3^2 = 9, \quad 9 - 5 = 4$ This matches the original expression, so this is the correct option.
