C/D? I get why A and D throw people off since nologging ops are a big fail for logical standby, but B is kind of a distractor because ROWID types aren't actually blocked, while BFILE is. Pretty sure it's A, C, D but wouldn't be shocked if someone mixed up B and C.
A/C/D lines up with what I've seen in the official docs and most Oracle exam practice. If you want to double check, I'd read the Oracle Data Guard guide and run through any lab questions on logical standby.
A/C/D
