Which of the following would be considered an executable file?

An executable file is a type of file that contains a program capable of being executed or run as a program in the computer. The primary characteristic of such files is that they contain binary code that the computer can directly execute when the file is opened.

EXE files are a standard format for executable files on Windows operating systems, meaning that they contain instructions and data that tell the system how to perform specific tasks when executed. When a user double-clicks an EXE file, the operating system recognizes it as a program and initiates its execution.

In contrast, PDF files, DOC files, and CSV files serve different purposes. PDF files are used for document presentation, DOC files are typically word processing documents, and CSV files are used for data storage in a tabular format. None of these types contain executable code that prompts the computer to perform an operation, hence they do not qualify as executable files.
