You have a large PDB, `DATA_PROD`, and need to create a new PDB, `DATA_TEST`, as a point-in-time copy for testing purposes, minimizing storage consumption and creation time. `CDB01` is configured to use ACFS (Oracle Automatic Storage Management Cluster File System) and `DATA_PROD` is open in READ WRITE mode. Which command should you use to achieve this goal efficiently?

The DATA_PROD PDB is large and frequently updated.

sql CREATE PLUGGABLE DATABASE data_test FROM data_prod;

sql CREATE PLUGGABLE DATABASE data_test FROM data_prod SNAPSHOT COPY;

sql CREATE PLUGGABLE DATABASE data_test FROM data_prod FILE_NAME_CONVERT=('data_prod','data_test');

sql CREATE PLUGGABLE DATABASE data_test AS CLONE FROM data_prod;
