The correct answer to this question is: c. Both of the mentioned.

Explanation:

1. Strong Literature Survey: A robust literature survey provides a comprehensive background on the existing knowledge related to the research topic. It helps identify gaps in current knowledge, informs the research direction, and establishes a foundation for the new study.

2. Case Studies: Case studies offer in-depth insight into specific instances or applications of the research topic, allowing researchers to gather qualitative data and derive practical implications and nuances.

Combining both approaches ensures a well-rounded research framework that is deeply informed by existing knowledge while also applying that knowledge to real-world scenarios or specific examples. This integrative approach enhances the validity and relevance of the research findings.
