C Correct answer
Explanation

  • Generally, rocks can be divided into three major types based on the process of their formation
  • Igneous rocks are formed by the solidification and cooling of magma in volcanic areas, 
  • While sedimentary rocks are formed by a low-temperature accumulation of sediments in tectonic basins and topographical sinks. 
  • Metamorphic rocks on the other hand are formed by application of temperature and pressure on pre-existing rocks
