What are two characteristics of Oracle SQLcl (SQL Developer Command Line)?

"Oracle SQLcl" (SQL Developer Command Line) is a lightweight, command-line interface for interacting with Oracle Databases. It has two key characteristics: "Tracks database schema changes" (B), through integration with tools like Liquibase, allowing DBAs to monitor and manage schema evolution; and "Ability to execute SQL batch files" (C), enabling automation of multiple SQL statements in scripts. "Creates isolated development environments" (A) is not a feature of SQLcl, as it’s a client tool, not a virtualization platform. "Available in the OCI Cloud Shell by default" (D) is incorrect, as OCI Cloud Shell provides a general terminal but does not pre-install SQLcl. Oracle’s SQLcl documentation confirms these capabilities.
