Hey there!
The distributive property is when you take one number and multiply by a quantity within parentheses and once multiplied and out of the parentheses it is the same value.
A is a simple addition problem.
C shows the associative property
D shows the commutative and associative property.
B shows that an expanded value is the same as something multiplied by something else in parentheses. Therefore, the answer is B.
I hope this helps!
