We have to establish a definite relationship between research scholar and scientist.
In figure 1 we get "no research scholar is a scientist" and in figure 2 we get "some research scholar are scientists". This forms a complementary set of conclusions, either of them is possible but NOT both.
Hence ONLY "some research scholar are scientists" is not a DEFINITE conclusion. So option 2 alone is invalid. So 3 & 4 are correct.

In the second fig, option 2 is satisfied, however in fig 1 it isn't. So if there is any doubtful case so we have to reject it.

(What is S and P here between ?) Anyway. If we would have 1st(no A+I) or 4th figure (No A+I). All conclusions would be invalid. 2nd option is not possible.
(1)
