For any two sets A and B, (A − B) ∪ (B − A) =

(a) \((A-B)\cup A\)

(b) \((B-A)\cup B\)

(c) \((A\cup B)-(A\cap B)\)

(d) \((A\cup B)\cap(A\cap B)\)

Solution

By definition,

\[ (A-B)\cup(B-A)=A\Delta B \]

Also,

\[ A\Delta B=(A\cup B)-(A\cap B) \]

Therefore,

\[ (A-B)\cup(B-A)=(A\cup B)-(A\cap B) \]

Answer

\[ \boxed{(A\cup B)-(A\cap B)} \]

Correct option: (c)
