The answer is "Option a and Option f"
Explanation:
In the given question option a and option f is correct because both commands use the "cp" command, which is used to copy files and in this command, in option a, it uses the file "from cs250 to cs150", and an option "f" uses the "cs250 with '.h' that is a file extension", and the wrong choice can be defined as follows:

Answer:
Change Control System
Explanation:
The Change Control System is a collection of processes that allow change requests to be analysed, approved, declined, and then managed.
HOW IT WORKS
A change request enters the change control system. The change request is written, not verbal. The change request form follows a predetermined route as to how it’ll be analysed, either by the project manager, a change control board, or both.
When the change control board approves or declines the change request the change requester is informed of the project decision. All decisions on change requests are documented for future reference.
