Answer:

It's A or C, but I'm 99.99% sure it is definitely A.

Step-by-step explanation:

I think it's "A. commutative, distributive, and addition" because "+4" and "-x" get switched from "+4 -x" to "-x +4" which is the commutative property. The commutative property states that you can add or multiply in any order and still get the same answer.

For example,

a + b = b+ a.

1 x 2 =  2 x 1.

3 + 5 = 5 + 3.
