A Correct answer
Explanation

In Informatica PowerCenter, $ denotes a Session Parameter (runtime values specific to a session) and $$ denotes a Mapping Parameter (defined at mapping level, reusable across sessions). The number of dollar signs distinguishes the scope - single $ for session-level, double $$ for mapping-level parameters. This is a standard naming convention.
