How can you modify a Flask CLI command to accept multiple values for an option named tags using the command pattern?

A@click.option('--tags', nargs=2) def cmd(tags): print(tags)

B@click.option('--tags') def cmd(tags): print(tags.split(','))

C@click.argument('tags', nargs=-1) def cmd(tags): print(tags)

D@click.option('--tags', multiple=True) def cmd(tags): print(tags)

Step-by-Step Solution

Solution:

Step 1: Understand multiple values in click options
Using multiple=True allows the option to be passed multiple times and collects values as a tuple.
Step 2: Compare other options
@click.option('--tags') def cmd(tags): print(tags.split(',')) manually splits a string, which is less clean; @click.argument('tags', nargs=-1) def cmd(tags): print(tags) uses argument, not option; @click.option('--tags', nargs=2) def cmd(tags): print(tags) limits to exactly 2 values.
Final Answer:
@click.option('--tags', multiple=True)\ndef cmd(tags):\n print(tags) -> Option D
Quick Check:
Use multiple=True for multi-value options [OK]

Quick Trick: Set multiple=True to accept repeated options [OK]
