Read the given statements 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 statements. Statements: I. Some A are B. II. All C are B. Conclusions: I. Some B are A’s is a possibility. II. No C is A. III. All A are C.

II. All C are B.
The minimum possible diagram for the given statements is as follows:
Conclusion:
(i) Some B are A is a possibility - True (The conclusion “Some B are A’s is a possibility” is true, because something that is already true is always possible.).
(ii) No C is A - False (no direct relation is given between them, so it might be possible, cannot be certain).
III. All A are C - False (no direct relation is given between them, so it might be possible, cannot be certain).
Only conclusion I follows
Thus, the correct answer is "Option 1."
