Question 1381Navigation General

The correct answer is C) geographical position of the body. The center of a circle of equal altitude, plotted on the surface of the Earth, represents the geographical position of the celestial body being observed. This is because the circle of equal altitude is a line on the Earth's surface where the observed body has the same altitude, and the center of this circle corresponds to the point on the Earth's surface directly below the body. The other options are incorrect because they do not accurately represent the relationship between the circle of equal altitude and the position of the observed body. The dead reckoning position and assumed position of the observer are not directly related to the geographical position of the body, and the assumed position of the body is not the same as its geographical position.
