Resposta:

According to the news report, a 7.1-magnitude earthquake occurred near the Philippines, which is a common natural event in that region. This event is a result of the region's geological structure.

The correct answer is option C) the location of the region over an area of tectonic plate boundaries, making it unstable.

This is because the Philippines is situated in the Pacific Ring of Fire, where several tectonic plates converge, resulting in frequent seismic and volcanic activity. The country is located near the boundary between the Eurasian Plate and the Philippine Sea Plate, which makes it prone to earthquakes.

In this context, the formation of the region's geological structure, characterized by the presence of tectonic plate boundaries, is the primary factor that contributes to the occurrence of earthquakes. The region's location in an area of tectonic plate boundaries makes it unstable, increasing the likelihood of earthquakes.

Therefore, the correct answer is option C) the location of the region over an area of tectonic plate boundaries, making it unstable.
