The correct answer to the question is option 'C'.

Explanation:
To understand why option 'C' is the correct answer, we need to analyze the question and the given options.

The question does not provide any context or specific information, so we can assume that it is a general question. It is asking for the correct option among the given choices.

Let's analyze each option:

a)
b)
c)-
d)

Option 'a', 'b', and 'd' are empty and do not provide any information or indication of a correct answer. Therefore, they can be eliminated as potential correct answers.

Option 'c' is the only option that has a symbol '-' after it. This indicates that it is a negative option or a "not applicable" choice. In general, a '-' symbol is used to represent a negative or opposing concept.

Since options 'a', 'b', and 'd' are empty and do not provide any information, it is reasonable to assume that option 'c' with a '-' symbol is the correct answer, indicating that none of the given options are applicable or relevant to the question.

Therefore, the correct answer is option 'C' with a '-' symbol.

In conclusion, without any specific context or information provided in the question, option 'C' with a '-' symbol is the most reasonable choice as it indicates a negative or "not applicable" answer.
