Q.
If $A=\{2,4,6,7\}$ and $B=\{6,7,9,10\}$, then find the value of $(A \cup B)-(A \cap B)$. Write the given steps in correct order.
(A) $A \cup B=\{2,4,6,7,9,10\}$ and $A \cap B=\{6,7\}$.
(B) Given $A=\{2,4,6,7\}$ and $B=\{6,7,9,10\}$.
(C) $(A \cup B)-(A \cap B)=\{2,4,9,10\}$.
(D) $(A \cup B)-(A \cap B)=\{2,4,6,7,9,10\}-\{6,7\}$.
