Final Answer:
The best way to prepare for research is option C: Look for books on the topic before looking for periodicals or websites.
Step-by-step explanation:
Option C suggests a structured and effective approach to research. Beginning by looking for books on the topic provides a solid foundation for understanding the subject matter comprehensively. Books often offer in-depth information, historical context, and a broader perspective. After gaining insights from books, one can then proceed to explore periodicals and websites for more current and specific details. This sequential method ensures a well-rounded understanding of the topic. Conversely, options A, B, and D either overlook the importance of foundational research through books (A, B) or lack a systematic approach (D).
Option C is the answer.
