1. Option C

2.

The correct  order is

1. Option C

As per the theory of vitalism, there exists a vital force with in a living substance/molecule which is lacking in a non living thing and hence an organic molecule/substance that are found is living organism cannot be produced by inorganic molecule/substance, rather they can be produced by living things only

Friedrich Ludwig Hünefeld was the first to cyrstallize protein for the first time in history in year 1840. And structure of DNA was first identified in year 1953 by Francis Crick and James Watson.

Thus the correct  order is

The element oxygen was discovered, urea was synthesized, proteins were crystallized, he structure of DNA was discovered
