Answer 1

The correct option is (c) Atomic mass unit

Best explanation: The Atomic mass unit is a standard unit of mass that measures mass on an atomic or molecular scale. One unit of it is practically equal to 1.66056×10^-24 g. 1 amu is defined as a mass that is almost equal to one-twelfth of the mass of one carbon – 12 atom.
