Solution

The correct option is A Carbon
Carbon is chosen as the reference atom to determine the relative atomic mass because the scientist used to get the molecular mass in whole number and it made calculations easier. Earlier Oxygen and Hydrogen were used as the reference for relative mass measurements.
