The correct answer identifies the three fundamental elements necessary for navigating by dead reckoning: starting point, distance, and azimuth.

Dead reckoning is a navigation method where the navigator calculates their current position based on a known initial position by using distance traveled and direction. The starting point acts as the reference location from which the journey begins. Distance is the measure of how far one has traveled from that starting point, which is crucial for determining the current position. Finally, the azimuth, or compass direction, defines the angle or bearing from the starting point to the destination; this directional information allows for accurate navigation along a planned route.

Understanding these elements is vital in military operations, where precise navigation can affect mission success. The other options include various elements, such as speed and elevation, which, while important in different contexts of navigation, do not serve as the core components of dead reckoning specifically.
