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:
$a\cdot a^(-1)=a^(-1)\cdot a=1.$
