For every subsets $A$ and $B$ of a non-empty set $X$, the operation $\odot$ is defined as
$$\mathrm { A } \odot \mathrm { B} = \mathrm { X } \backslash ( \mathrm { A} \cup \mathrm { B} )$$
For every subsets $K$ and $L$ of X satisfying the condition $K \subseteq L$, what is the result of the operation
$$( \mathbf { X } \backslash \mathbf { L } ) \odot ( \mathbf { L } \backslash \mathbf { K } )$$
A) $X$\\
B) K\\
C) L\\
D) $X \backslash K$\\
E) $X \backslash L$
