The correct answer is

Fixed circular orbits

Niels Bohr proposed that electrons move only in certain permitted circular paths around the nucleus, called orbits or shells (K, L, M, N…), each with a fixed energy.

While revolving in these discrete orbits, an electron does not radiate energy, so it does not spiral into the nucleus. Electron clouds belong to the later quantum mechanical model, not Bohr's model.

Hence, the answer is Fixed circular orbits.
