A - LRS can be converted to ZRS directly.
Indirectly, you can also convert RA-GRS by first stepping down to LRS, then stepping up to ZRS. But in this case I'd say it's a NO.
The premium tier also supports LRS, ZRS or Premium storage. However, there's no way to say storage 1 & storage 3 support conversion to ZRS. As such, my answer will be A.
A
you can directly convert (not migrate) from LRS to ZRS for Storage Account v2 only.
Premium fileshares can be also converted by performing service request.

If this is the case, Should there be an option for storage 1 + 2 it'd be correct as well.

StorageV2 (general purpose v2) accounts can be converted to ZRS.
Storage1 and Storage2 are both StorageV2 accounts, but Storage2 uses RA-GRS, which cannot be directly converted t
E.
the question is not asking what possible for direct conversation. the only choice that make sense to me is E.
• Storage1 can be directly converted to ZRS.
• Storage3 can also be directly converted to ZRS.
• Storage2, although currently using RA-GRS, can be switched to LRS first and then converted to ZRS.
Storage3 cannot be converted to ZRS because it is a BlobStorage account.
So, if we go by your words then answer should be Storage 1 & 2 ONLY. But we don't have that option.
So, correct answer is A. Storage 1 ONLY
