Correct choice:

The distributive property of multiplication over addition acts by the rule:

$a\cdot (b+c)=a\cdot b+a\cdot c.$

Incorrect choices:

1. Communicative Property of Multiplication - $a\cdot b=b\cdot a;$

2. Multiplicative Identity - the "multiplicative Identity" is 1: $a\cdot 1=1\cdot a=a;$

3. Multiplicative Inverse Property - a multiplicative inverse is a reciprocal: $a\cdot a^{-1}=a^{-1}\cdot a=1.$

A and B

Step-by-step explanation:

Do the vertical line test! A and B pass the test, however the circle doesn't. That means the circle is not a function.
