The fme_feature_type format attribute contains...

• A. the full schema of the source feature type.
• B. the path to the source dataset.
• C. the name of the dataset's original features (for example, a file, feature class, database, or table).
• D. the SQL statement to extract features from a database.

Answer: (C)

The fme_feature_type attribute holds the name of the original dataset’s feature type. In other words, it stores the identifier FME uses for the source layer as provided by the reader—such as the file name (without extension) for a shapefile, or the feature class/table name in a database. This is not the full schema, a path, or an SQL statement; it’s simply the name that identifies where those features came from.

So you’d see something like the layer or dataset name (for example, Buildings from a buildings shapefile or a city_blocks table in a database) reflected here. This helps with provenance and with downstream writers that need to know which source feature type produced the current features.
