The correct answer is Option 2 i.e. All conclusions follow.
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. Some doctors are umbrellas → True (As some doctors are tigers, and all tigers are umbrellas, so, some doctors are umbrellas is also true.)
II. Some tigers are umbrellas → True (As all tigers are umbrellas, so, some tigers are umbrellas is also true.)
III. Some buses are umbrellas → True (As some umbrellas are buses, so, some buses are umbrellas is also true.)
Hence, All conclusions follow.
