I practiced a question similar to this, and I remember that you can't just replace the program; it usually requires more steps, so option B seems wrong.

I'm not entirely sure, but I feel like option D might also be true because configuration settings can change with new versions.

I think option C is definitely correct since I remember reading about the need for backup and restore during upgrades.
