If an access control has a fail-safe characteristic and not a fail-secure characteristic, what does that mean?

A.
It defaults to no access.

B.
It defaults to being unlocked.

C.
It defaults to being locked.

D.
It defaults to sounding a remote alarm instead of a local alarm.

Explanation:
A fail-safe setting means that if there were a power disruption, which
would affect the automated locking system, the doors would default to being
unlocked. A fail-secure configuration means that a door would default to being
locked if there were any problems with the power.
