Three statements are given, followed by three conclusions numbered I, II and III. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements.

Statements:

I. All dahlias are lilies.

II. All sunflowers are lilies.

III. Some dahlias are hibiscus.

Conclusions:

I. Some sunflowers are not dahlias.

II. Some hibiscuses are not lilies.

III. Some lilies are hibiscus.​​

I. All dahlias are lilies.

II. All sunflowers are lilies.

III. Some dahlias are hibiscus.

I. Some sunflowers are not dahlias. (Not follows, The statement "All sunflowers are lilies" and "All dahlias are lilies" doesn’t imply any exclusion between sunflowers and dahlias. )

II. Some hibiscuses are not lilies. (Not follows, Since all dahlias are lilies and some dahlias are hibiscuses, this doesn't guarantee that some hibiscuses are not lilies. They could all be lilies.)

III. Some lilies are hibiscus. (Follows,  This is true because since some dahlias are hibiscuses, and all dahlias are lilies, some lilies are hibiscuses.)

So, Only conclusion III follows.

Thus, correct option is (b).
