What property is shown by the equation

Distributive is a(b+c)=ab+ac
and remember -(b+c)=-1(b+c)

commutative is a+b=b+a

associative is
a+(b+c)=(a+b)+c

1.
moved numbers in paretnasees
commutatuve A

2. moved arenthasees
associative, B

3. distributive, isn't listed so I assume 'oposite of a sum property'
C

4. swtiched order
commutve A

1. A
2. B
3. C
4. A
