Answer 2

Option A

Step-by-step explanation:

The answer is "seismograph" or option A. A seismograph is a tool that records duration and force of a Earthquake when it strikes. It works by responding to ground motions because it's very sensitive to vibrations. So when the device picks up a huge vibration is quickly records how long it lasts and how strong the vibration was.
