Step 1: Place each event on a timeline.
The Diamond Sutra was printed in China in 868 CE, Marco Polo reached Italy from China around 1295 CE, Gutenberg printed his Bible around 1455 CE, and the Bengal Gazette came out in 1780.
Step 2: Sort these dates.
Ordering them from earliest to latest gives 868, then 1295, then 1455, then 1780.
Step 3: Convert dates back to events.
That sequence is Diamond Sutra, Marco Polo's return, Gutenberg's Bible, Bengal Gazette, which is II, IV, III, I.
Hence, the correct answer is option (D) II, IV, III, I.
