Answer OPTION: A) 10

Explanation:
The code defines a global variable x with a value of 10.

Inside the immediately-invoked function expression (IIFE), a local variable x is defined with a value of 20.

The foo() function is called from within the IIFE.

When foo() is called, it looks for the value of x in its own scope and then in the outer scope, which is the global scope.

So, foo() logs the value of the global variable x, which is 10.

Hence, the output will be 10.
