The correct answer is option A. This means that 3 and 4 are the correct conclusions, that we can say fit 100%.
These are the statements: All the research scholars are psychologists. Some psychologists are scientists.
The 1st conclusion says "All the research scholars are scientists. " This can not be true, because we can't say that this conclusion is correct in every case. The 2nd conclusion isn't true either, bc just some psychologists are scientists doesn't mean that they are some research scholars in the larger group of psychologists that are also scientists.

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.

We always take basic diagram for conclusions you are right when the situation demands we take alternative diagram but here there is no need to take alternative diagram.

That's true you take either of the possibility in your answer hence option A. If the q mentioned the word POSSIBILITY then statement 2 will also be included.

(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.

There is also a possibility that the whole (rs) comes b/w psychologists and scientists common part so I think A is also a valid answer.

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.

From fig -1, we get option D to be correct I.e some scientists are psychologists.
But it's not the answer.
But it's not the answer.

Second option also correct how to say 3 & 4 is correct. Any one give proper explanation friends?

For a statement to be true, it must be common in both the diagrams, unlike 2nd option.
