Mount Vesuvius is an example of a volcano that is a steep-sided volcano formed by an alternating series of lava flows and pyroclastic deposits and marked by repeated eruption.

The correct answer is Stratovolcano.

Explanation:

A stratovolcano is that volcano that is composed of strata and layers of hardened lava. These volcanoes are characterized by very explosive eruptions, which happens in the case of Mount Vesuvius. This volcano has in its interior material with high density and at high temperatures such as hot lava, pumice and ashes among others.

The shape of the stratovolcanoes is steep and its type of lava is viscous, which cools before being shot over long distances.

Given this information we can say that the correct answer is stratovolcano.
