Answer: C
Explanation:
"Commute" means travel so commutative property is when one of the terms or parentheses move elsewhere in the expression: 72 + (28 + 93) = (28 + 93) + 72
"Associate" is partner so associative property is when the parentheses switch partners but the order of the terms remains the same: 72 + (28 + 93) = (72 + 28) + 93
The operation between the terms is addition.
