What is wrong with this plugin code?

module.exports = (on, config) => {
  on('before:browser:launch', (browser = {}, launchOptions) => {
    launchOptions.args.push('--disable-gpu')
  })
}

AUsing default parameter for browser is not allowed

BThe event name 'before:browser:launch' is invalid

ClaunchOptions.args is not an array

DThe event handler does not return launchOptions

Step-by-Step Solution

Solution:

Step 1: Understand event handler requirements
before:browser:launch handlers must return modified launchOptions object.
Step 2: Check code behavior
Code modifies launchOptions.args but does not return launchOptions, so changes are ignored.
Final Answer:
The event handler does not return launchOptions -> Option D
Quick Check:
Return launchOptions after modification [OK]

Quick Trick: Return modified launchOptions in before:browser:launch [OK]

Common Mistakes:

Forgetting to return launchOptions
Assuming event name is wrong
Misunderstanding launchOptions structure
