    A)  Associative property

    B)  Commutative property

    C)  Distributive property    

    D)  Closure property

    Correct Answer: C

    Solution :

    (c) Distributive property means   \[a\times \left( b+c \right)=\left( a\times b \right)+\left( a\times c \right)\]     or \[-\,a\times \left( -b+c \right)=\left( -a\times -b \right)+\left( -a\times c \right)\]
