Correct answer
Either conclusion I or II follows.
Why this answer is correct
The least possible Venn diagram according to the above statement is:
Conclusion:
I. Some Book are Pen - False( This can be the possible conclusion not definite hence conclusion doesnot logically follows)
II. No Book is Pen - False( This can be the possible conclusion not definite hence conclusion doesnot logically follows)
Conclusion of I and II forms complementary pair.
Some + No, When both the conclusion are false is considered as either or pair.
Hence, the correct answer is either conclusion I or II follows.
