If Tom spends all day making dishes and Jerry spends all day making dishes, there will be a total of 16 + 14 = 30 dishes at the end of the day.
If Tom spends all day building fences and Jerry spends all day building fences, there will be a total of 4 + 7 = 11 fences at the end of the day.
Therefore, Tom could have either (8 dishes, 2 fences) or (4 dishes, 3 fences) at the end of the day. Both of these scenarios are possible based on the information given in the problem. Choice C includes both of these possibilities, so it is the best choice.
