Answer:

c)Banana * daco;

Gps has fostered many benefits in our society, but have also added some risks. What is a risk of gps?
kozerog [31]

GPS is a global positioning system that tells direction and routes. Some risks that come along with GPS are inaccuracy, distraction, and lack of knowledge.

<h3>What is GPS?</h3>

GPS is a radio navigation system based on the satellite and is used to navigate the directions with the help of the signals. Though it has many benefits also has disadvantages. It sometimes does not show accurate routes and direction that is too long.

The navigation system causes distraction during driving and may cause an accident. Too much reliance on GPS causes a lack of knowledge in remembering the directions and places. It may sometimes lead to crime as the saved information and be leaked.

Therefore, GPS has advantages and disadvantages too.
