Which one of the following statements with regard to volcanoes is not correct?

Stratovolcanoes produce lava flows that initially follow valleys but are highly resistant to erosion.
The surrounding areas can remain highlands, lava ridges or mesas.
Hawaiian shield volcanoes are eroded by streams that form deeply carved valleys with steeply sloping heads.
The system of streams on a dissected volcano cone is not a radial drainage pattern.

The statement “The system of streams on a dissected volcano cone is not a radial drainage pattern” is not correct.
Volcano cones, being elevated, roughly symmetrical peaks, naturally lend themselves to a radial drainage pattern where streams flow outwards from the central high point in all directions. When a volcano cone is dissected by erosion over time, the streams carving into its slopes typically maintain this radial arrangement.
Statements A, B, and C are generally correct regarding volcanic landforms and erosion. Stratovolcano lava flows can be resistant to erosion, creating distinct features. Erosion on large shield volcanoes like those in Hawaii does result in deeply carved valleys. The radial drainage pattern is characteristic of conical or dome-shaped landforms like volcanoes or isolated hills/mountains.
