For commutative property,


x-y\\e y-x

Where


x,y\in R

Where x and y are real numbers


\begin{gathered} \text{Where } \\ x=4,y=3 \end{gathered}

For the commutative property of whole numbers,


\begin{gathered} x-y\\e y-x \\ x-y=4-3=1 \\ x-y=1 \\ y-x=3-4=-1 \\ y-x=-1 \\ 4-3\\e3-4 \end{gathered}

Hence,


\begin{gathered} x-y\\e y\\e x \\ 4-3\\e3-4 \end{gathered}

The answer is the second option.
