I think it should be E, because A is not a definite conclusion.
All betas are gammas could mean:
1. The set Betas and the set Gammas, are equal/same.
2. The set betas is a subset of the set Gammas.

In case of No. 2, it is possible for the set betas to not overlap with the set Alphas, thus rendering Option A invalid.

Careful--you've assumed E in drawing your diagrams. It's also possible for A and G not to intersect, so E is out. An important fact about "some" is that it does not preclude "all." It just means > 0. So I could say "some dogs are mammals." This is true, even though of course ALL dogs are mammals. If it were not, we'd have the negation--NO dogs are mammals, and we know that's false.
