  • A A*b = b*a
  • B (a*b)*c = a*(b*c)
  • C (b ο c)*a = (b*a) ο (c*a)
  • D None of the above
Correct Answer: Option A
Explanation:
A binary operation '*' defined on a set A is said to be commutative only if a*b=b*a, ∀a, b∈A.

If (a*b)*c=a*(b*c), then the operation is said to associative ∀ a, b∈ A.

If (b ο c)*a=(b*a) ο (c*a), then the operation is said to be distributive ∀ a, b, c ∈ A.
