D Correct answer
Explanation

Option (1) is true, as for any three integers a,b and c, a + (b + c) = (a + b) + c Therefore, addition is associative. Option (2) is true as 5 - (8 - 3) is not equal to ( 5 - 8) - 3. Or 5 - 5 is not equal to - 3 - 3. Option (3) is true, as for three integers a, b and c, a  x ( b x c ) = ( a x b ) x c Therefore, all the three options are correct.
