Question

where do earthquakes most commonly occur?
randomly around the world
only in the ocean
along tectonic plate edges

Explanation:

Earthquakes occur due to the movement of tectonic plates. These plates interact at their boundaries (edges), causing stress to build up. When this stress is released suddenly, it results in an earthquake. So, earthquakes most commonly occur along tectonic plate edges. They don't occur randomly as there's a geological reason (plate movement) behind them. Also, they aren't restricted to the ocean as there are continental - plate boundaries (e.g., the San Andreas Fault on land).

Answer:

C. along tectonic plate edges
