Which of expressions illustrates the associative property? ab + bc

a ( b + c ) = ab + bc

a ( b + c ) = (a + b ) + c

a + b + c = c + b + a

c)   a ( b + c ) = (a + b ) + c

Step-by-step explanation:

The associative property is a property of some binary operations, which means that rearranging the parentheses in an expression will not change the result. In propositional logic, associativity is a valid rule of replacement for expressions in logical proofs.
