What will be the output of the following code snippet?

from selenium import webdriver
options = webdriver.FirefoxOptions()
options.add_argument('--private')
driver = webdriver.Firefox(options=options)
print(driver.capabilities['moz:firefoxOptions']['args'])

B['--headless']

C[]

DKeyError exception

Step-by-Step Solution

Solution:

Step 1: Understand FirefoxOptions argument addition
Adding '--private' argument to FirefoxOptions stores it in the args list inside capabilities.
Step 2: Access capabilities dictionary
driver.capabilities['moz:firefoxOptions']['args'] returns the list of arguments passed, which includes '--private'.
Final Answer:
['--private'] -> Option A
Quick Check:
FirefoxOptions args list = ['--private'] [OK]

Quick Trick: Options args appear in capabilities under 'moz:firefoxOptions' [OK]

Common Mistakes:

Expecting headless by default
Assuming args list is empty
Thinking accessing keys causes error
