Answer: Choise A and Choise B.
Step-by-step explanation:
Given the following expression:

You can simplify it in order to find equivalent expressions.
Appying the Distributive Property, you get:

So:
1. If you add the like terms, you get this equivalent expression:

2. But if you factor out 3, you get the following equivalent expression:

Therefore, the expression shown in Choice A and Choise B are equivalents to the expression 
Answer:
d) A = π(
)
