Now that you have seen the behavior for the remove$()$ and reverse$()$ methods, let's revise one more time to concept of mutable and immutable objects and how they affect memory management in Python. Select the answer to correctly complete the expected output:

$>>>$ d $=\{\text{'}$part$\text{'}$:$[1,2,3,4],\text{'}$pi$\text{'}$: $\text{'}3\mathrm{.}141592653589793\text{'},3$: $\{6$:$\text{'}$A$\text{'},36$:$\text{'}$B$\text{'},56$: $[6,7,8]\}\}$
