Answer to Question 1

B

Answer to Question 2

The opportunity cost of second executive's work is 800,000 . The reason is that since each executive can perform any work that they other can then it makes sense to change the second executive's job so that he is now doing the most highly valued work  that with the 1,000,000 value. That leaves the 800,000 job undone which means that becomes the opportunity cost of the second executive's work.
