Detailed Solution & Explanation
In the event of a natural calamity (such as an earthquake, flood, cyclone, or epidemic), the most appropriate and effective method to collect primary data is the Personal Interview method. Under this method, the investigator meets the victims or respondents directly and collects the necessary information on the spot. Since the situation requires urgent, accurate, and direct assessment, personal interaction is highly efficient for gathering reliable data in a short span. Other methods like questionnaires are impractical because communication and mailing systems are typically disrupted during calamities.
Hence, **Option A** is the correct answer.
