• A. $\left(X\Delta Y\right)\Delta \left(Z\Delta W\right)$ is $\{1,2,3,5,6,7,9,10\}$
• B. $\left(X\Delta Z\right)\Delta \left(Y\Delta W\right)$ is $\{1,2,3,5,6,7,9,10\}$
• C. $\left(X\Delta Y\right)\Delta \left(Y\Delta W\right)$ is $\{1,3,8,10\}$
• D. $\left(X\Delta Y\right)\Delta \left(Z\Delta W\right)$ is $\{1,2,3,4,5,6,7,8,9,10\}$

Answer 1

The correct option is A $\left(X\Delta Y\right)\Delta \left(Z\Delta W\right)$ is $\{1,2,3,5,6,7,9,10\}$
