Urey and Miller attempted to mimic conditions on early Earth to illustrate how the origin of life may have occurred billions of years ago. Which statement would provide the most evidence that early Earth's conditions were suitable for the formation of carbon-based life? options:

The atmosphere contained heavy isotopes of hydrogen, like tritium, in the water molecules.

Liquid from the sampling probe contained amino acids.

The air sampled from the primitive atmosphere contained diatomic nitrogen rather than ammonia.

The pH of the ocean waters was more acidic with less salinity than oceans today.

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite   shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
