Answer OPTION: C) ReferenceError: Cannot access 'x' before initialization

Explanation:
This code will throw a ReferenceError because the variable x is accessed before it is declared. JavaScript has a concept called "hoisting" where variable and function declarations are moved to the top of their respective scopes. However, hoisting does not include the initialization step.

So, even though the variable x is declared in the outer scope, it is not accessible inside the foo() function before it is explicitly declared with let x = 20.

I think that it will print 10 and the new value of x will be 20
Am i correct?
