Question 1529Navigation General

The correct answer is C) Western. The last stars that should be observed at evening stars are those with an azimuth in the western quadrant. This is because as the night progresses, the stars rise in the east, reach their highest point in the south, and then set in the west. Therefore, the stars with an azimuth in the western quadrant will be the last ones visible before they disappear below the horizon. The other options are incorrect because stars in the northern, southern, and eastern quadrants will not be the last to be observed at evening stars.
