The Idempotent Law for set union states that:

  • A.A ∪ a = a
  • B.A ∪ b = b ∪ a
  • C.A ∪ ∅ = a
  • D.A ∪ u = u

Answer: A

The Idempotent Law states that when an operation is applied to an element with itself, the result is the same element.

For set theory, this means:

1. A ∪ A = A (Idempotent Law of Union)

2. A ∩ A = A (Idempotent Law of Intersection)
