Which keyword is used to transfer control from a function back to the calling function?Select one:go backswitchgotoreturn

The correct keyword used to transfer control from a function back to the calling function is return.

Explanation:

• In most programming languages, the return statement is used to exit a function and optionally return a value to the location where the function was called.
• The other options listed do not serve the same purpose:
  • go back is not a standard keyword in programming.
  • switch is typically used for conditional branching, not for returning control.
  • goto is a statement that can jump to a labeled statement but does not specifically return control to a calling function.

In summary, among the options given, return is the appropriate choice for transferring control back to the calling function.
