What is the mechanism which produces the continuous series of narrow pulses of electromagnetic radiation at precise rates from neutron stars or pulsars in our universe?

(a)   The regular passage across the Earth of a narrow, directed beam of electromagnetic radiation from a very compact and rapidly rotating neutron star.
(b)   The regular ringing or oscillation of the solid surface of a very compact neutron star, in the manner of a ringing bell or a vibrating wine glass.
(c)   The rapid orbiting of a neutron star around a black hole, the intense gravitational field of which periodically focuses emitted electromagnetic radiation from the neutron star towards the Earth.
