Conclusions:

I: Some males are doctors → Doesn't Follow (As per the above Venn diagram it is a possibility that some males are doctors because there is no direct relation given between males and doctors so we can not define direct relation between them)

This possibility scenarios can be shown using the below Venn diagram:

Here, From the above Venn diagram, some doctors are male but from the first Venn diagram, No direct relation between doctors and males so it is a possibility we can not say anything about "Some males are doctors".

II. All engineers are Indians → Follow (As per the above Venn diagram there is a direct relation between Engineers and Indians so we can define the direct relation between them)

Hence, the correct answer is "Only conclusion II follows".
