The opportunity cost of building a fence for Jerry is the number of dishes he could have made if he chose to make dishes instead of building fences. Therefore, the opportunity cost of building a fence for Jerry is 14 - 7 = 7 dishes.

Since Tom is more productive in making dishes (16 dishes) than building fences (4 fences), he should spend his day making dishes. 
Similarly, Jerry is also more productive in making dishes (14 dishes) than building fences (7 fences), so he should spend his day making dishes.

Therefore, the best choice is: 
Tom should make dishes all day and Jerry should make dishes all day. 
Answer: A and A 
 Both Tom and Jerry are more productive in making dishes, so they should choose to make dishes all day.
