Stars of which type are the smallest in diameter?

white dwarfs
brown dwarfs
red dwarfs
neutron stars
A typical neutron star has a mass between about 1 and 2 solar masses, with a cor­re­spond­ing radius of just about 12 km. Some of them (pul­sars), rotate as quickly as once per 33-mil­lisec­ond, so their radius must be very small not to break the light speed limit at the surface level.
