Recent volcanic activity in different parts of the world supports the inference that volcanoes are located mainly in
1)the centers of landscape regions
2) the central regions of the continents
3) zones of crustal activity
4) zones in late stages of erosion

Option (3)

Explanation: Zones of crustal activity is also known as the tectonic activities. This is the region, where plates undergoes convergent, divergent or transform movement.

These volcanoes are formed when plates undergoes collision, that means convergent plate boundary, where the denser plate gets subducted beneath the less denser plate.

And the data collected by studying about the different volcanoes, helped in  the determining that the volcanoes are mostly located at the zone where crustal activities constantly goes on.

Thus, the correct answer is option (3).
