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. No A is B.
II. All C are D.
III. Some C are B.
Conclusions:
I. Some D are B.
II. Some B are C.
III. All C are B.
A.Only conclusion III follows.
B.Both conclusions I and II follow.✓ Correct
C.Only conclusion II follows.
D.Both conclusions I and III follow.
Explanation
From 'All C are D' and 'Some C are B', some of those C that are B are also D, so Some D are B (Conclusion I follows). Also, 'Some C are B' directly implies Some B are C (Conclusion II follows). Conclusion III does not follow as only some C are B.
