Step 1: Bohr’s model of the hydrogen atom.
In the Bohr model, the hydrogen atom consists of a nucleus (proton) and an electron orbiting it in discrete energy levels or orbits. The energy of the electron in a given orbit is quantized, and the lowest orbit corresponds to the lowest possible energy.
Step 2: Lowest energy level.
The lowest orbit, also known as the ground state, corresponds to the minimum energy, where the electron is closest to the nucleus and has the least energy.
Step 3: Conclusion.
Thus, the lowest orbit in the Bohr model corresponds to the minimum energy, corresponding to option (B).
