In this question, there are three statements followed by conclusions numbered I and II. You have to take the given statements to be true even if they seem to be at variance from commonly known facts and then decide which of the given conclusions logically follow from the three statements. 
Statements:

• All books are ledgers.
• All pens are keys.
• Some pens are books.

Conclusions:

• A. if only conclusion I follows
• B. if only conclusion II follows
• C. if neither I nor II follows
• D. if both I and II follow
