C Correct answer
Explanation

Mapping parameters in Informatica PowerCenter are designed to hold values that change between sessions (like dates, file paths, or external values). They're set before session execution. Session variables are runtime-modifiable, while UDFs are for custom logic, making mapping parameters the best choice for frequently changing external values.
