Which of the following describes the unit of containment that an application is constrained to on an operating system?

A process is an instance of a computer program that is being executed, serving as a container that provides an application with its own isolated memory space, file handles, and other resources managed by the operating system, ensuring its operational boundaries.

A directory is a file system structure used to organize files and other directories, not a unit of containment for an application's execution or resources.

A console is typically a text-based interface for interacting with a program or operating system, not a unit of containment for an application's runtime.

A thread is a lightweight unit of execution within a process that shares the process's resources, but the process itself is the primary unit of containment.
