🔹 A. Because pointers are smaller than data blocks

🔹 B. Because data blocks are stored elsewhere on disk

🔹 C. Because pointers allow direct access to any block

🔹 D. Because pointers reduce external fragmentation

💡 Difficulty: medium | ✅ Correct: A

Q3. A system uses linked index blocks, each holding 100 pointers. When a client accesses block 120 of a file, what sequence of reads occurs?
