The correct option is C Cuvier
Jean Leopold Nicolas Frederic, Baron Cuvier (23 August 1769 – 13 May 1832), also known as George Cuvier, was a French naturalist and zoologist, sometimes referred to as the "founding father of palaeontology". He had expanded Linnaean taxonomy grouping classes into phyla and incorporating both fossils and living species into the classification. Cuvier proposed that now-extinct species had been wiped out by periodic catastrophic flooding events. So, the corrects answer is " Fossil extinct bird-like reptiles were first found out by Cuvier".
