Question 1572Navigation General

The correct answer is C) Eastern. At evening stars, the first stars that should be observed are those in the eastern quadrant. This is because as the earth rotates, the eastern horizon is the first area of the sky to become visible as the sun sets and darkness falls. Stars in the eastern quadrant will be the first to appear, before stars in the other quadrants become visible. The other answer choices are incorrect because stars in the southern, northern, or western quadrants will not be the first to appear at evening stars. The eastern quadrant is the correct choice based on the principles of celestial navigation and the movement of the earth relative to the stars.
