Concept:Syllogism deals with drawing valid conclusions from given statements using set relationships.
Explanation:• Statement 1: Some shirts are biscuits → There is an overlap between shirts and biscuits.
• Statement 2: No biscuit is book → Biscuits and books have no common elements.
• Conclusion I: Some shirts are books. Since the biscuits that are shirts are not books, we cannot conclude that any shirt is a book. So I does not follow.
• Conclusion II: Some books are biscuits. This directly contradicts "No biscuit is book". So II does not follow.
• Thus, neither conclusion follows.
Answer:D. if neither I nor II follows
