Ilmenite and rutile, abundantly available in certain coastal tracts of India, are rich sources of which one of the following?

1. Ilmenite (FeTiO3) is an iron-titanium oxide mineral, and Rutile (TiO2) is primarily titanium dioxide. 2. Both Ilmenite and Rutile are the principal ores used for the extraction of Titanium. 3. These minerals are found abundantly in the beach sands of certain coastal tracts of India, particularly in states like Kerala, Tamil Nadu, Odisha, and Andhra Pradesh. 4. Therefore, Ilmenite and Rutile are rich sources of Titanium. 5. They are not primary sources of Aluminium (sourced from Bauxite), Copper (sourced from chalcopyrite, etc.), or Iron (sourced from hematite, magnetite, etc., though Ilmenite contains iron).
