By which variable of the sys module can we access command line arguments?

The correct answer is D. argv. sys.argv is the correct variable - it's a list where argv[0] is the script name and subsequent indices hold any command-line arguments passed to it.

Explanation

sys.argv is the correct variable - it's a list where argv[0] is the script name and subsequent indices hold any command-line arguments passed to it. The distractors are all plausible-sounding but don't exist in the sys module: argsv (option A) is simply a misspelling of argv, arguments (option B) is JavaScript's keyword for accessing function arguments, and args (option C) is a common variable name used in custom code (e.g., from argparse) but is not a built-in sys attribute. Memory tip: argv mirrors C's int main(int argc, char *argv[]) - Python borrowed the name directly from C, so if you remember that argv means "argument vector," you'll never confuse it with the alternatives.
