I think have no answer.
The attribute “OS_LOGIN” represents the external user.

A is definitely wrong, as STATUS is always an integer.
B is sort of wrong, because PRIV_USER always has the user-name, if authenticated (internally or externally).
C is wrong, as NAME can’t be EXTERNAL… anything.
D — maybe right…
E — could be right — as the external authentication plug-in prbbly has a log.
F — assuming it’s not a TYPO, then “PROXY_PRIV” doesn’t exist, if it’s PRIV_USER, then it’s the same as answer-B, still wrong. Proxy has nothing to do with this anyway.

I’d lean toward D then E.

should be E.

$ perror 1045
MySQL error code 1045 (ER_ACCESS_DENIED_ERROR): Access denied for user ‘%-.48s’@’%-.64s’ (using password: %s)

OS_LOGIN

A string representing the external user (empty if none). The value may differ from USER, for example, if the server authenticates the client using an external authentication method. This attribute appears only if the NAME value is “Connect” or “Change user”.

not sure if the answers are right.

The PROXY privilege is needed to enable an external user to connect as and have the privileges of another user. To grant this privilege, use the GRANT statement. For example:
