Answer:
B. A single, specific amount of energy is associated with each movement of an electron between energy levels.
Step-by-step explanation:
As we know by the Bohr's theory that total energy of an electron in a given energy state is given by

now here if we will find the change in energy of two states then it is given by


now when this specific amount of energy is absorbed by the electron then only it will change the state of energy.
so here correct answer will be
B. A single, specific amount of energy is associated with each movement of an electron between energy levels.
