Several Lines of Evidence Now Suggest That Large and Complex

Several lines of evidence now suggest that large and complex organic molecules can exist or could evolve in outer space,from which the building blocks of life could be formed.Which is NOT one of these observational findings?

A) radio astronomical observations of large organic molecules in giant molecular clouds
B) discovery of organic molecules inside some meteorites
C) discovery by the Viking landers of large organic molecules in the Martian regolith
D) laboratory experiments in which electrical sparks passing through a combination of simple gases such as H₂O, H₂, N₂, and CO₂ produced large organic molecules
