Circle represents Doctors, Triangle represents Professors and Rectangle represents Journalists.

So, the number of Doctors who are Professors also is the region where the portion of the Circle is overlapped by the Triangle only.

So, 4 + 3 + 1 = 8

Thus, 8 is the number of Doctors who are Professors but not Journalists.

Hence, 8 is the correct answer.
