उत्तर
This statement is True.
Explanation:
Under high temperature and pressure over millions of years, dead plants (along with other organic materials) get slowly converted into coal. This process occurs in the Earth’s crust, where heat and pressure cause the plant material to undergo chemical changes, eventually forming coal, which is an important fossil fuel.
