D)All of the above are correct.

Quizplus · Accepted Answer

Rhyolitic lavas do not flow as far from the vent as basaltic lavas do due to their high viscosity.

Answer: B
 Rhyolitic lavas cool much more slowly than basaltic lavas do due to their high silica content, which increases the melting point of the magma.

Answer: C
 This statement is false. Rhyolitic volcanoes can produce pyroclastic debris just like any other type of volcano.

Therefore, the correct answer is A and B.
