Option 1 : Roasting

The correct answer is Roasting.

Concept:

Mineral: A naturally occurring substance with uniform chemical composition is called a mineral.
Ore: An ore is a mineral from which a metal can be extracted in a profitable way.

According to the reactivity of metals, different methods are employed to extract metals from their ores.

Reactivity series of metals:

Electrolytic reduction: Electric current is passed through the molten state of metal ores. Metal being positively charged is deposited over the cathode.
Thermit process: It is a chemical reaction between metal and metal oxide. A lot of heat energy is liberated in this reaction.
Calcination: The heating of carbonate ores in the limited supply of air to convert them into oxides is known as Calcination.

In making decisions about important questions, it is desirable to be able to distinguish between ‘strong’ arguments and ‘weak’ arguments. ‘Strong’ arguments are those, which are both important and directly related to the question. ‘Weak’ arguments are those, which are of minor importance and also may not be directly related to the question or may be related to a trivial aspect of the question. The questions below is followed by two arguments numbered I and II. You have to decide which of the arguments a ‘strong’ argument is and which a ‘weak’ argument is.
