What is the approximate elevation at Point C?

The correct choice indicates an approximate elevation of 900-920 feet at Point C. This elevation range is likely determined based on a variety of factors including topographical maps, previous measurements, or surrounding landmarks that can provide context for estimating elevation.

In scenarios like Search and Rescue operations, understanding elevation is crucial for navigation and strategy planning. Point C's selection as being in the 900-920 feet range suggests that this data has been corroborated by various geographic or environmental factors that would influence the elevation readings.

Elevation estimations typically utilize contour lines on maps, GPS data, or other navigational tools that indicate height above sea level. The key to arriving at this answer involves understanding and interpreting the geographical data accurately to match it with the provided elevation options. Therefore, knowing the specific features or landmarks near Point C that correspond with its elevation can further validate why this particular range is correct.
