Which component can have multiple feature types?

• A. Workspace
• B. Reader
• C. Writer
• D. Transformer

Answer: (B)

In FME, a feature type is a layer or dataset with its own schema (geometry and attributes). A data source can contain more than one of these feature types, and the component that brings all of them into the workspace is the Reader. The Reader can expose multiple feature types from a single source—for example, a geodatabase that holds several feature classes like roads, rivers, and parcels. Each feature type is read as its own stream with its own structure, letting you route, transform, and write them separately. Writers write to a destination feature type, and transformers work on the features they receive, but typically a single Reader handles multiple feature types because a source can have multiple layers or classes.
