c. pyroclasts

Explanation:

An explosive eruption happens when a lot of gas gets trapped in the magma, this, combined with the high viscosity of the magma, produces a pressure build and eventual explosive eruption of magma of the volcano. During this kind of volcanic eruptions, the expelled material can immediately begin moving down the sides of the volcano forming a pyroclastic flow, the resulting fragments of magma in this kind of eruptions are called tephra (or pyroclasts) and consist in small and large pieces of rock that are hardened, solidified, or compressed version of an originally loose pyroclastic deposit.
