Solution

The output of the given JavaScript code will be:

d. 11

Explanation:

  1. We declare two variables, a with a value of 5 and b with a value of 11.
  2. We also declare an object obj with a property a and a value of 10.
  3. The with keyword in JavaScript allows us to access the properties of an object without explicitly referencing the object name.
  4. Inside the with(obj) block, we use the alert() function to display the value of b.
  5. Since b is not a property of the obj object, JavaScript will look for b in the outer scope, which is the global scope.
  6. In the global scope, b has a value of 11, so the alert() function will display 11 as the output.
