Several Lines of Evidence Now Suggest That Large and Complex

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

A) the discovery of large organic molecules on and under the soils of Mars and the Moon
B) laboratory experiments in which electrical sparks passing through a combination of simple gases such as H₂O, H₂, N₂, and CO₂ produced large organic molecules
C) radio astronomical observations of large organic molecules in giant molecular clouds
D) the discovery of organic molecules inside certain meteorites that arrived upon Earth
