This question does not provide any specific information or context, so it is difficult to determine the correct answer. However, since the question mentions that the correct answer is option 'C', we can assume that there are multiple choices and option 'C' is the correct one.

To analyze this question further, let's break it down into different sections and consider each option:

a)
b)
c)
d).

Since there is no information given for each option, it is impossible to provide a definitive answer without any context. However, we can make some assumptions based on common patterns in multiple-choice questions.

Assuming that this is a multiple-choice question, we can consider the following possibilities:

1. Option 'A': This could be a possible answer, but without further information, it is impossible to determine its correctness.
2. Option 'B': This could be a possible answer, but again, without context, it is difficult to evaluate its correctness.
3. Option 'C': According to the question, this is the correct answer. However, without any context, we cannot explain why it is correct.
4. Option 'D': This could be a possible answer, but without any information, we cannot determine its validity.

Overall, since the question does not provide any context or specific information, it is impossible to explain why option 'C' is the correct answer. It is important to have clear and specific questions to provide accurate and detailed explanations.
