Answer:
Option (A)
Explanation:
Explosive volcanic eruption refers to the eruption of volcano that produces a large amount of pyroclastic materials, volcanic blocks and ashes, and cinders and 'aa' materials.
The pahoehoe forms from the smooth flowing of the lava due to its high viscosity. It forms ropy surfaces and generally results from a non-explosive volcanic eruptions. On the other hand, 'aa' are angular pieces of lava that are formed during a volcanic eruption. Volcanic ashes are the ashes that are produced along with the pyroclastic materials.
Cinders are the pyroclastic materials that are formed due to the explosion of a volcano. These are similar to the pumice rock, that are ejected to a distant areas.
Thus, the correct answer is option (A).
