B Correct answer
Explanation

A seismograph measures and records earthquake shocks by detecting ground vibrations. It consists of a suspended mass that remains stationary while the ground moves during an earthquake, creating a record of the seismic waves. This helps scientists study earthquake patterns, magnitudes, and epicenters. Seismographs cannot measure temperature, air pressure, or time.
