Question 1311Navigation General

The correct answer is B) 3.0 millibars. In low latitudes, the range of the diurnal variation of pressure (the difference between the highest and lowest pressure readings during the day) can be up to 3.0 millibars. This is due to the stronger solar heating and atmospheric circulation patterns that occur near the equator, which can cause more pronounced fluctuations in barometric pressure over the course of a day. The other answer choices are incorrect because 0.5 millibars is too low, 6.0 millibars is too high, and 10.0 millibars exceeds the typical range observed in low-latitude regions.
