B) she is still utilizing a GPS, although she may not be using all of its potential to store, organize, retrieve, and analyze data.
C) she is using only the components of a remote sensing system, because she is not storing, organizing, retrieving, or analyzing data.
D) she is not using a GIS, because she is not using all of the system's potential to store, organize, retrieve, and analyze data.
