    as it is all answers are wrong. Definitively it’s not “E” because of the word “outgoing”. Maybe “B” but even after testing (with the config above) I could login on my 3rd password attempt.

    Value configured on the device using the ip ssh authentication-retries integer command plus one. This means:
    “ip ssh authentication-retries 1” would give the result of 2 attempts. It is in the wording, a retry means you already attempted it once.
    Actually E is correct as the command “ip ssh timeout ” specifies the timeout when attempting to authenticate.
