Analogy between Carbon and Corundum

The given question is an analogy question, where we need to find the relationship between two pairs of words. In this question, we are given a pair of words, Carbon and Diamond, and we need to find a word that is related to Corundum in a similar way as Diamond is related to Carbon.

Carbon is an element that exists in different forms, and one of its forms is Diamond. Diamond is a crystalline form of carbon, which is the hardest known mineral and is used in jewelry and cutting tools. Hence, we can say that Diamond is a type or a form of Carbon.

Corundum is a mineral that is composed of aluminum and oxygen, and it is the second hardest mineral after diamond. It is commonly used as an abrasive and in the production of gemstones. Therefore, we need to find a word that is related to Corundum in a similar way as Diamond is related to Carbon.

Answer

The correct answer to the given question is option D, Ruby. Ruby is a type of Corundum that is red in color due to the presence of chromium. Ruby is commonly used as a gemstone and is known for its hardness and durability. Therefore, we can say that Ruby is a type or a form of Corundum, just like Diamond is a type or a form of Carbon.

Conclusion

Analogies are used to test our reasoning and analytical skills by identifying the relationships between different pairs of words. In this question, we have learned that Diamond is a type of Carbon, and Ruby is a type of Corundum. By understanding the relationship between these pairs of words, we can solve similar analogy questions with ease.
