The statement "The archive remains locked whenever the custodian is absent" is logically equivalent to which option?
- If the archive remains locked, the custodian is absent.
- If the archive is unlocked, the custodian is absent.
- If the archive is unlocked, the custodian is present.
- None of these
Explanation
“Whenever the custodian is absent, the archive remains locked” means: If the custodian is absent, then the archive is locked.
The contrapositive of “If P, then Q” is “If not Q, then not P.” Therefore, if the archive is unlocked, the custodian is not absent—that is, present.
