In the Bohr model, as the principal quantum number $n$ increases, the total energy of the electron becomes less negative (indicating an increase in total energy), the kinetic energy decreases because the electron is moving in a larger orbit at a slower speed, the potential energy increases (becoming less negative) due to the electron being further from the nucleus, and the orbital radius increases. This means all the given statements are correct in the context of the Bohr model.
