    The answer is; B

    This detected radio source, determined to be pulse-like, was identified to be coming from a pulsating star called a pulsar. The charged particle emitted by the rapidly rotating star is emitted as synchrotron radiation in the radio spectrum. The pulsation was discovered to be at the rate of 30 times a second. Crab nebula is a nebula cloud made from a supernova.
