B! 
For multiple choice, it often helps to get rid of answers that don't make sense immediately. 
For example, D doesn't show anything. C is showing a property of addition that order doesn't matter, and so does A. B is the only one that shows multiplication into a parentheses, which is the distributive property!

welshfella · Answer

a(b + c) = a*b + a*c  is the distributive property

welshfella · Answer

also a(bc)= ab*ac

I think there's a typo in one of the choices

Ah then it is number D, as the distributive property is that a(b+c) = ab + ac!
