Key Concepts to Consider
- Context of the Question: The first step in understanding the correct answer is to examine the subject matter of the question. Is it related to mathematics, science, literature, or another subject?
- Options Analysis: Look at all the options (a, b, c, d) and evaluate each one based on the criteria specified in the question.
- Fundamental Principles: Identify the core principles or concepts that apply to the question. This is crucial in determining why option 'C' stands out as the correct choice.

Justification for Option 'C'

- Supporting Evidence: Often, the correct option is supported by facts, theories, or data that validate it. Look for any evidence that supports why option 'C' is the most appropriate choice.
- Comparison with Other Options: Dissect the other options (a, b, d) to understand their shortcomings. Why do they not fit the criteria set by the question? This will further solidify the reasoning behind choosing option 'C'.
