The answer is not a because the equator has a low pressure because the sun heats up the air and the hot air rises thus creating a low pressure on the land. It also exists in the 60 degree latitude the sub - polar low pressure belt because compared to the polar winds the winds blowing from the equator are relatively hotter than the polar winds , thus they force the winds to rise up creating a low pressure so the correct answer is option d.
