Let a binary operation '*' be defined on a set P. The operation will be commutative if ___________.

Correct option is A

Commulativity requires that the result of the operation remains unchanged regardless of the order of the operands.

Mathematically, this is expressed as a*b=b*a for all elements a,b in the set P.

​Example: For P = R, addition (+) is commutative since a+b=b+a for any real numbers a,b.
