Is this a trick question? It seems like all of the answer choices have roots in ancient India, at least according to my Bing search.

SORRY!

Uhm, Im not sure.

SmokeyBrown · Answer

Fair enough.
If I had to choose, I might say "the invention of gunpowder"? Because it's true that they used gunpowder in ancient India, but I'm not sure if they "invented" it exactly... So that's the only one that stands out to me as a possible answer
