b. an unmanned aerial system (uas)
c. a geographic information system (gis)
d. the global positioning system (gps)

The correct answer would be D. the global positioning system (GPS).

GPS is a type of radio navigation system which enables the user to determine their exact location in the land, sea, and in even air.

With advancement in technology, it also enables the user to determine other factors such as velocity, time-zone, weather condition all around the world.

It uses the network of around 30 satellites orbiting the earth at around 20,000 kilometers altitude.

In wildlife, the GPS tracker device is implanted or collared in the animals, which sends and stores the data via a satellite system.

it would lead to upper respiratory infections and pneumonia.
