Oracle AI Database provides a native VECTOR data type specifically for storing vector embeddings. The uploaded course source identifies VECTOR as the correct native column type.
Oracle's official AI Vector Search documentation states that the built-in VECTOR data type provides the foundation for storing embeddings directly alongside relational business data. A table can therefore define a vector column in the same way it defines conventional Oracle columns, for example doc_vector VECTOR .
This native representation is important because Oracle AI Database can apply vector-specific SQL operations and vector indexes directly to stored embeddings. Applications can combine similarity search with relational predicates, JSON processing, graph operations, spatial queries, and standard SQL without moving embeddings into a separate specialized vector database.
Although Oracle may internally use storage mechanisms such as SecureFiles for vector representation, BLOB is not the logical SQL column type developers use for AI Vector Search embeddings . JSON and VARCHAR2 are likewise general-purpose data types and do not provide native vector semantics.
Therefore, A is correct.
