Choose the odd one out.

PUT
END
OWL
ARM E. IFL

The odd one out is C, OWL. The other four options are all programming languages. OWL is a knowledge representation language, which is used to represent knowledge in a way that can be used by computers. It is not a programming language, and therefore does not belong in the same group as the other four options.

A. PUT is a command in the C programming language that is used to write data to a file.
B. END is a keyword in the C programming language that is used to indicate the end of a function.
D. ARM is a programming language that is used to create applications for mobile devices.
E. IFL is a programming language that is used to create interactive fiction.
