A) scoria and other vesicular basalt
B) basalt mostly formed in lava flows
C) felsic and intermediate lava flows and tephra
D) pillow basalts
E) none of these

Composite Volcano

A type of volcano built up by many layers (strata) of hardened lava, tephra, pumice, and volcanic ash.

Felsic Lava

Lava that is high in silica content, resulting in high viscosity and explosive eruptions; it is characteristic of volcanoes at continental margins.

Tephra

Rock fragments and particles ejected by a volcanic eruption which include ash, lapilli, and volcanic bombs.

Final Answer :
C
Explanation :
Composite volcanoes, also known as stratovolcanoes, are characterized by eruptions that produce a variety of materials, including felsic (high silica content) and intermediate lava flows, as well as tephra (volcanic ash, lapilli, volcanic bombs). These materials layer upon each other, creating the composite structure.
