How is interferometry used in radio astronomy?
A)   Signals from a radio source are combined with an equivalent signal delayed in time to produce interference, thereby increasing the angular resolution of the telescope.
B)   Signals from different places around the dish of a radio telescope are combined to produce interference and increase the angular resolution of the telescope.
C)   Signals from two or more different radio telescopes are combined to produce a single image of greater angular resolution than from any one telescope alone.
D)   Signals from different parts of a radio source are combined to increase the angular resolution of the telescope.
