Answer:

C. 1

Step-by-step explanation:

Commutative property says that changing the order of the operands does not change the result. This can be expressed as:

a+b=b+a

Using the previous information, we can say:

x+4=4+x

And rewrite the equation as:

\frac{x+4}{x+4}

Since the numerator and denominator are the same:

\frac{x+4}{x+4}=1\\\forall x\neq-4
