Why does this Laravel route cause an error?

Given this Laravel route code, what error will it cause? Route::get('/user/{id}', function ($userId) { return "User ID: $id"; });

Laravel

Route::get('/user/{id}', function ($userId) {
    return "User ID: $id";
});

A No error; the route works and returns the user ID

B Syntax error due to missing semicolon after return statement

C Route not found error because the URL pattern is invalid

D Undefined variable $id error because the closure uses $userId but returns $id

💡 Hint

Check variable names inside the function.

The closure receives $userId but tries to use $id which is undefined, causing an error.
