The Associative property of addition states that when three or more numbers are added, it does not matter how they are grouped, the sum is the same. Then:

$a + (b + c) = (a + b) + c$

Based on this and having the expression $3 + 19- 12$ , we can apply the Associative property as following:

$(3 + 19) - 12 = 3 + (19 - 12)$

Therefore, the expression that illustrates the Associative property of addition is the one shown in the Third option.
