Assertion: India is richly endowed with non-ferrous metallic minerals.
Reasoning: Bauxite is a non ferrous metallic mineral.
Answer & explanation
Correct answer: option 4
India is endowed with a rich variety of mineral resources due to its varied geological structure. Bulk of the valuable minerals are products of pre-palaezoic age and are mainly associated with metamorphic and igneous rocks of the peninsular India. The vast alluvial plain tract of north India is devoid of minerals of economic use. India is poorly endowed with non-ferrous metallic minerals except bauxite.
