Answer 1

Hint: We know that ores are very important rocks or sediments that have very important metals, minerals inside it. The valuable metals and minerals can be taken out from the ores by performing different metallurgical processes and purification processes.

Complete step by step solution:
Red lead is a very important inorganic compound. The molecular formula of red lead is \[P{b_3}{O_4}\]. It is mainly used as a red pigment due to its colour. It is used to manufacture batteries and paints. Red lead or \[P{b_3}{O_4}\]is also known as Minimum. So we can write Read lead-Minium, that is a-s.
Litharge is an oxide of lead. The molecular formula of litharge is $PbO$. So from the formula we can say that it leads to monoxide. We can write Litharge-Lead monoxide, that is b-p.
Galena is a very important ore. It is also known as Lead Glance. It is one of the most important ore of lead. The molecular formula of Galena is $PbS$. It is a sulphide ore. So we can write Galena-An ore of lead, that is c-q.
Cassiterite has a molecular formula of $Sn{O_2}$. It is one of the most important ore of tin. So we can write Cassiterite- An ore of tin, that is d-r.
So from the above explanation and discussion it is clear to us that the correct answer of the given question is : Read lead-Minium; Litharge-Lead monoxide; Galena-An ore of lead; Cassiterite- An ore of tin that is the option: C. a-s; b-p; c-q; d-r

Hence, the correct answer is C.

Additional information:
Metallurgy is a very important part of materials science engineering. In metallurgy we learn about different chemical and physical properties of ores,metals and minerals.The concept of metallurgy is used to purify ores and obtain valuable metals and minerals from the ores.

Note: always remember that Red lead, \[P{b_3}{O_4}\] and Minimum are the same thing. Litharge has a molecular formula of $PbO$. Galena is a sulphide ore. The molecular formula of Galena is $PbS$.
Cassiterite or $Sn{O_2}$ is an important ore of tin.
