Assertion: Prefix is written in front of the root word.
Reason: A primary prefix is like cyclo- for ring compounds and secondary prefixes are substituents or side chains like alkyl groups ex. methyl, ethyl.
A. Both the Assertion and Reason are correct and Reason is the correct explanation for Assertion.
B. Both the Assertion and Reason are correct but Reason is not the correct explanation for Assertion.

Hint:In the branch of chemical nomenclature, the IUPAC nomenclature is basically a method of naming the organic compounds as suggested and recommended by the International Union of Pure and Applied Chemistry .
In chemistry, many numbers of prefixes, suffixes and infixes are generally used to describe the type as well as position of the functional groups in any compound.
Complete step-by-step answer:In order to name an organic compound, firstly you must first memorize a few basic names. In general, the base part of the name mainly reflects the number of the carbons in which you have assigned to be the parent chain. The suffix of the name on the other hand reflects the types of different functional groups present on/within the parent carbon chain. Other groups which are attached to the parent chain are basically called as substituents.
Prefixes as per the rules are added prior to the root of the compounds in IUPAC nomenclature. Prefixes are very useful as they indicate the presence of the side chains or any substituent groups in a given organic molecule. These prefixes sometimes also offer insight into the cyclic or acyclic natures of the organic compounds in question.
We should remember that prefixes in an IUPAC nomenclature can be generally classified into primary prefixes and secondary prefixes.
1. Primary Prefixes Indicates the cyclic or acyclic nature of any given compound. For example: The prefix ‘cyclo’ is used for cyclic compounds.
2. Secondary Prefixes Indicates the presence of the side chains or any substituent groups. A classic example of such types of prefixes would be the ‘CH3’ group, which is called the methyl group.
We should remember that prefixes in an IUPAC nomenclature can be generally classified into primary prefixes and secondary prefixes.
Therefore, we can clearly see that Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
Hence, the correct option is B.

Note:To avoid the long and tedious names in our normal communication, the official IUPAC recommendations of nomenclature are not always followed in daily practice, except when it is very necessary to give an unambiguous or absolute definition to a compound. IUPAC names can many times be way more simple than older names, as with ethanol, in place of ethyl alcohol.
