As time progresses,the pulse rate for most solitary pulsars:

Question

Quizplus · Accepted Answer

The correct answer is B, as the pulsar slows down since rotational energy is being used to generate the pulses. This effect is known as spin-down, and it occurs because the radiation emitted by the pulsar carries away energy from its rotation, causing it to slow down over time. However, there are rare exceptions where some pulsars speed up, but these are due to more complex phenomena such as accretion of matter or glitch events.
