Read the given statement(s) and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statement(s).

Statements:-

1. All crows are black.
2. Some black things are beautiful.
Conclusions
I. Some crows are beautiful.
II. Some beautiful things are black.​​

Statements:-

1. All crows are black.
2. Some black things are beautiful.

I. Some crows are beautiful. (False, because all crows are black and some black things are beautiful, it doesn't mean that those beautiful black things are crows).
II. Some beautiful things are black. (True, it is directly stated: "Some black things are beautiful" implies the same as "Some beautiful things are black").

So, only Conclusion II follows.

Thus, correct option is (b).
