An instrument through which a pair of overlapping photographs is viewed to see a three-dimensional model is a:
सही उत्तर: ख) Stereoscope
A stereoscope presents each overlapping photo to one eye so the brain fuses them into a 3D view.

Ground control points (GCPs) in photogrammetry and image rectification are:
सही उत्तर: ग) Points identifiable on the image whose ground coordinates are known
GCPs link image coordinates to ground coordinates, allowing scaling, orientation and georeferencing.
