Answer: The correct answer is : (2) all inorganic rocks except igneous rocks are formed from other rocks
Explanation: Igneous rocks are formed by the solidification of magma, the process is slow if it is in the crust and fast if it is on the surface.
Sedimentary rocks are formed on the surface of the earth by processes of erosion and alteration of pre-existing rocks.
Metamorphic rocks have been formed by the evolution of another previous rock due to the environment to which it is subjected that may be hotter, colder or of a different pressure.

Hotspot in geology is the surface manifestation of a plume that rises from deep in the celestial body's mantle.
Divergent margins also known as rift zones, shield volcanoes tend to form as two oceanic plates pull slowly apart and magma effuses upward through the gap.
The sites based on history that has volcanism related to a hot spot or divergent margin are Hawaii and the mid-ocean ridge. Hawaiian volcanoes within the Pacific Plate are caused by anomalous volcanism.
