Which French chemist was one of the first scientists to synthesise organic compounds such as formic acid, methane and acetylene from their elements?

Correct option is C

The French chemist who was one of the first scientists to synthesize organic compounds from their elements was Marcelin Berthelot.
 Berthelot was a pioneer in the field of organic synthesis and made many important contributions to the study of chemical reactions and thermodynamics.
 In 1856, he was the first to synthesize an organic compound, urea, from its inorganic components, and he went on to synthesize many other organic compounds, including formic acid, methane, and acetylene, from their elements. His work laid the foundation for modern organic chemistry.
