PLEASE HELP ME ASAP!!! Which example represents an individual vs. individual conflict in “The Ornithopter”?

The technology needed to make many of Leonardo's inventions is not available during his lifetime.

Leonardo has an opportunity to make a good living, but it involves making weapons of war, which he believes is "a beastly madness."

The duke imagines the ornithopter as a weapon of war, while Leonardo imagines it as a thing of beauty and innovation.

Leonardo struggles in making a decision about doing work for a purpose he does not agree with.
