Final answer:
The choice of survey method should be based on what data collection method will generate the most complete and generalizable information within the time frame and budget limitations.
Step-by-step explanation:
The choice of survey method can be made by answering the question: "What data collection method will generate the most complete and generalizable information within the time horizon and without exceeding the allowable expenditure for data collection?" (Option C). This question addresses the key considerations in choosing a survey method, such as the completeness and generalizability of the information collected, the time frame, and the budget limitations. Factors like cost, researcher comfort, number of validation methods, and customer comfort are not as critical in determining the most appropriate survey method.
