Explanation:

GPS (Global - Positioning System) is a satellite - based navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. It is mainly used for determining location. Tidal predictions are related to oceanographic and astronomical factors, amount of marine life is related to ecological studies, air - sea interactions are related to meteorology and oceanography, and temperature is measured by thermometers. None of these are the main function of GPS.

Answer:

C. Location
