What makes it incorrect is the wrong match of the properties. The correct answer is actually the opposite. The first expression is a manifestation of associative property while the second expression is a manifestation of commutative property.

Commutative property is the arrangement of order of algebraic terms. Associative property is the arrangement of order within a grouped quantity.
