Which syntax correctly defines a Cypress plugin function in the plugins file?

Aconst plugin = (on, config) => { return on('task', { myTask() { return null } }) }

Bexport default function(on, config) { on('task', { myTask() { return null } }) }

Cmodule.exports = (on, config) => { on('task', { myTask() { return null } }) }

Dfunction plugin(on, config) { on('task', { myTask() { return null } }) }

Step-by-Step Solution

Solution:

Step 1: Recall Cypress plugin export syntax
Cypress plugins use CommonJS syntax with module.exports to export the function.
Step 2: Analyze options for correct syntax
module.exports = (on, config) => { on('task', { myTask() { return null } }) } uses module.exports with arrow function and correct event handler setup. The other options fail: one defines a local const without export, another uses ES module export, and the last lacks any export.
Final Answer:
module.exports = (on, config) => { on('task', { myTask() { return null } }) } -> Option C
Quick Check:
Plugin export = module.exports function [OK]

Quick Trick: Use module.exports for Cypress plugins [OK]
