Answer:

C. Distributive property

Step-by-step explanation:

Distributive property says that

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

Consider left part of the expression

\dfrac{6x+9}{3}=\dfrac{1}{3}\cdot (6x+9)

By distibutive property,

\dfrac{1}{3}\cdot (6x+9)\\ \\=\dfrac{1}{3}\cdot 6x+\dfrac{1}{3}\cdot 9\\ \\=2x+3
