Which statements about door lock actuation are correct?

• A. A only
• B. B only
• C. Both A and B
• D. Neither

Answer: (C)

Door lock actuation is about how the latch is moved to lock or unlock the door, and it can be done by manual linkages or by electric or other actuators. If both statements describe valid aspects of how the latch can be driven—such as a mechanical path moving the latch directly and an electric actuator that also moves the latch—then the combined option is the right choice. In vehicle systems, it's common to have multiple ways to actuate a lock and to consider how each method affects reliability, speed, and safety (for example, the ability to override electronically with a manual operation if power is lost). Since both described aspects reflect real, workable ways doors can be actuated, choosing the option that says both are correct aligns with how door lock actuation is implemented.
