is an example to show thatA. addition of rational numbers is commutative.B. rational numbers are closed under addition.C. addition of rational number is associative.D. rational numbers are distributive under addition.

The question is incorrect.

In place of it shoulb be .

Now the question becomes ) {Here a = ,b = }

Now the operation performed is a + b = b + a

This is commutative property of rational numbers

(b)Incorrect the number obtained on the right side is not the added value, It has been changed from a + b to b + a.

(c)Incorrect the property is an example of commutativity not associativity.

{Associative property for addition - a + (b + c) = (a + b) + c}.

(d)Incorrect it’s not an example of distribution or distributive Property.

{Distributive property - a×(b + c) = a×b + a×c
