Show answer & explanation
Correct answer: B
Statement I is the associative law: changing the grouping does not change the result, so (x*y)*z = x*(y*z). Statement II is the distributive law: the * operation distributes over the + operation, so x*(y+z) = (x*y)+(x*z). Therefore, both I and II are correct.
