Let's match the pioneers of forensic science with their respective fields.
A. Calvin Goddard: He is considered the father of modern forensic ballistics, known for pioneering the use of the comparison microscope for firearm identification. So, A matches with II.
B. Karl Landsteiner: He discovered the ABO blood groups in 1901, which is the foundation of blood grouping and modern transfusion medicine. So, B matches with III.
C. Albert S. Osborn: He was a pioneer in the field of questioned document examination in North America, authoring the influential text "Questioned Documents." So, C matches with IV.
D. Mathieu Orfila: He is considered the father of modern toxicology. He was the first to use microscopy to assess blood and semen stains and made significant contributions to the study of poisons. So, D matches with I.
The correct set of matches is A-II, B-III, C-IV, D-I.
