I thought umount just unmounts it, not erase it?

A won't work, that's not how rm functions.

Wait, can you really erase a partition like that? Sounds risky!

A won't work, rm can't delete partitions like that.

B is the right one, it writes zeros to the partition.

I feel like I’ve seen a question like this before, and B definitely seems to be the command that would wipe the partition clean.

I’m a bit confused about A and B. I thought rm was for files, but does it really not affect partitions?

I remember practicing with dd commands, and I think B is correct. A just removes files, not the partition contents.

I think option B is the right one since it uses dd with /dev/zero, but I'm not entirely sure if it will actually erase everything.
