According to the Directions to Solve:

Read the conclusions and then decide which of the given conclusions logically follows from the two given statements, "disregarding commonly known facts".

So, if we just consider the 2 given statements:
All the harmoniums are instruments.
All the instruments are flutes (Conclusion 1).
which means, All the harmoniums are flutes (Conclusion 2).

So, Both Conclusions should be correct.

Short method is 100 & 50 method.

I think the answer is E.

The diagram in explanation shows only one situation that harmoniums are making a portion of instruments. But as per set theory, the complete set is also a subset of the given set. It can also be true that if all harmoniums are instruments, all instruments are also harmonium. Similarly in the second sentence.

In such case, option E is the answer.
