Concept:
This question tests general knowledge and business awareness regarding prominent chemical and mineral industries based in the state of Kerala, India.
Let us evaluate the acronym CMRL:
• C stands for Cochin (referring to Kochi, a major port city in Kerala where the corporate foundations are centered).
• M stands for Minerals (reflecting the company’s focus on processing mineral sands).
• R stands for Rutile (a major mineral consisting primarily of titanium dioxide, which the company chemical plant processes into synthetic rutile).
• L stands for Limited (denoting its status as a public limited corporate entity).
Combining these gives: Cochin Minerals and Rutile Limited.
Let us look at why the other options are incorrect:
• Option (B) introduces *Rubber*, which is a major agricultural commodity in Kerala but incorrect for this specific mineral sand enterprise.
• Option (C) introduces *Magnesite*, which is a different mineral compound altogether.
• Option (D) introduces *Restile*, which is a non-existent word in this company's title.
Therefore, Option (A) is the correct answer.
