Answer:
The correct option is: Total energy
Step-by-step explanation:
The Hamiltonian operator, in quantum mechanics, is an operator that is associated with the total energy of the system. It is equal to the sum of the total kinetic energy and the potential energy of all the particles of the system.
The Hamiltonian operator was named after the Irish mathematician, William Rowan Hamiltonis denoted and is denoted by H.
