After the seal has been broken, the signal is activated by pulling on which component?

• A. Lever
• B. Cable
• C. Button
• D. Pin

Answer: (A)

The key idea is how a signaling device is activated once its safety seal is removed. The lever acts as the direct mechanical trigger to start the signal. When the seal is broken, pulling the lever releases a latch or compresses a spring that sets the signaling mechanism into motion, giving you an intentional, immediate activation that’s easy to perform in a hurry or under stress. A cable would require the mechanism to be connected to something else and isn’t the typical single-step actuation for breaking seal scenarios. A button is a push action, which isn’t what this device uses for activation, and a pin is usually a safety or arming component rather than the sole way to trigger the signal. So pulling the lever provides the straightforward, reliable activation after breaking the seal.
