e correct answerWhich module in the python standard library parses options received from the command line?Optionsgetargmaingetoptos

The correct answer is getopt.

The getopt module in the Python standard library is designed for parsing command-line options. It provides a way to handle command-line arguments and options, allowing programmers to define both short and long options for their scripts. By using getopt, developers can easily manage various options passed to their programs when executed from the command line.

The other options mentioned do not accurately represent a module in the Python standard library for this specific purpose. Here's a brief clarification of the other options:

• getarg: This is not a recognized module in Python's standard library.
• main: This typically refers to the main function in Python scripts, which is used as an entry point, not for parsing options.
• os: This module provides a way of using operating system-dependent functionality, but it does not specifically handle command-line argument parsing.

Thus, amongst the options listed, getopt is the correct choice.
