Solution
The correct options are
A With the help of high altitude aerial remote sensing
B With the help of a polar satellite
Polar satellites are very near to the Earth with an altitude ranging 500-800km thus they are generally used for taking pictures of any location, whereas Geostationary satellite is placed nearly 3600km above the Earths surface; hence it is used for signalling and not for taking clear images of a particular place.
