There seems to be some confusion in the question as it does not provide any context or options for us to determine the correct answer. However, based on the given information, it is mentioned that the correct answer is option 'C'. Let's explore some possible interpretations and explanations for this answer.

Possible Interpretations:
1. The question might be referring to a multiple-choice question where options 'a', 'b', 'c', and 'd' are provided, and option 'C' is deemed correct. Since the options are not provided, we can't establish the exact context or subject matter of the question.

2. Another possibility is that the question is asking for a letter or code to represent a particular category, and in this case, 'C' is the correct answer. Again, without more information, we cannot determine the specific category or context the question is referring to.

Explanation for Option 'C':
As mentioned earlier, without additional context, it is challenging to provide a precise explanation for why option 'C' is the correct answer. However, we can make some general assumptions based on common practices or patterns in multiple-choice questions. Here are a few possible explanations:

1. Correct Order or Sequence: If the options represent a sequence or order, 'C' might be the correct answer because it fits the logical progression or pattern.

2. Alphabetical Order: In some cases, multiple-choice options are arranged alphabetically, and 'C' might be the correct answer simply because it falls in the middle of the sequence.

3. Contextual Knowledge: If the question is related to a specific subject or topic, 'C' might correspond to the most appropriate or commonly accepted answer based on the provided information.

Please note that these explanations are speculative and may not reflect the actual reason behind the correct answer. Without more information or specific context, it is challenging to provide an accurate and definitive explanation.
