Option 1 : Only B is true

The correct answer is Option 1, Every ore is mineral but every mineral is not an ore.

In the modern periodic table, there are 118 elements out of which 92 falls in the category of metals, 20 non-metals, and 6 metalloids.
Metals are extracted from ore and minerals contain both metals as well as non-metals.
For example, aluminium exists in two mineral forms that are clay and Bauxite. But aluminium is mainly extracted from bauxite which contains 70% aluminium oxide, i.e Bauxite is an ore of aluminium whereas clay is not an ore.
Hence, every ore is a mineral but every mineral is not an ore.
