He wanted to make inventions for other people. I know that might not be the awnser but that's what I think
The correct answer should be Leonardo did not intend for his inventions to do harm.
I saw on the Internet that B and D are incorrect, so we have to choose between A and C. A is also incorrect because Leonardo had much greater plans for his inventions that simply to investigate the properties of snow. This leaves us with C as the correct answer - he wanted to advance science, rather than create a bad invention.
