Option A is correct, as Autonomous database only supports logical migration, using DataPump/SQL*Loader/Golden Gate. B is incorrect as ADB does NOT support remote cloning. To prove this point, in one the steps mentioned for remote cloning('https://www.oracle.com/technical-resources/articles/cloud/migrate-db-to-cloud-remote-cloning.html') one has to connect to the Oracle Database Cloud Service compute node using an SSH public key. Autonomous Database does not allow to connect to the OS it is running on therefore, remote cloning is out of the option.

Autonomous Database does *not* support remote cloning. PDB cloning is valid for only regular databases.

B is correct starting in 12 it’s called remote cloning. https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&ved=2ahUKEwj9opjQg8nqAhXSK80KHcKlCZkQFjABegQIAhAB&url=https%3A%2F%2Fwww.oracle.com%2Ftechnical-resources%2Farticles%2Fcloud%2Fmigrate-db-to-cloud-remote-cloning.html&usg=AOvVaw1MlxT0yDolnl_asja0yX_L
