Answer:
The correct answer would be "it would be the worse situation as the total medical knowledge would decrease in a society".
If all the doctors would have the same level of knowledge about all aspects of medicine then it might be possible that none would be able to treat a particular disease as all would have limited knowledge about that disease.
In contrast, specialized doctors or surgeons have maximum knowledge about a particular organ which helps us in treating the disease efficiently.
For example, the cardiologist would have much more knowledge about the heart as compared to the general physician.
