Question 1312Navigation General

The correct answer is C) 1000 and 2200. In low latitudes, the diurnal (daily) variation of atmospheric pressure exhibits two high points - one in the late morning around 1000 and another in the late evening around 2200. This is due to the heating and cooling of the Earth's surface, which causes changes in air density and pressure throughout the day. The other options are incorrect because noon and 1600 do not correspond to the observed high points in low latitudes.
