C
Correct answer
Explanation
Source Qualifier is editable because it allows customization of the SQL query used to extract data from the source. Source and Target definitions are metadata that cannot be directly edited in the mapping designer.
AI explanation
In the Informatica PowerCenter Mapping Designer, source and target definitions are read-only there (they're edited in the Source Analyzer and Warehouse/Target Designer instead), but the Source Qualifier transformation is a mapping-level object and its properties (like SQL override, join conditions) can be edited directly in the Mapping Designer.
