Which statement best describes the capability of the BulkAttributeRenamer regarding attribute naming?

• A. It can only rename coordinates.
• B. It can add prefixes and suffixes to attribute names.
• C. It can remove attributes.
• D. It can generate new attribute values.

Answer: (B)

Renaming attribute names in bulk is about applying naming changes across many attributes at once. The BulkAttributeRenamer is best described as a tool for modifying the names themselves, not the data, and a common capability is adding prefixes or suffixes to attribute names. This makes naming consistent and can help indicate origin or versioning—for example, adding a source prefix like "src_" to all attributes or appending "_v1" to denote a version. It can handle many attributes in one operation, which saves time when preparing data for downstream processes.

It’s not about changing coordinate values or removing attributes, and it doesn’t create new attribute values. Generating or calculating values is handled by other transformers, while removing attributes is done by a different operator.
