The four satellites are needed to determine the location of an object using a GPS receiver.

Option: B

Explanation:

A GPS receiver specifically calculates the different speed of light (299,792 km / s) variations in the signals arriving from 4 or more satellites to determine the location of Longitude, Latitude and Highness.

There is requirement of four satellites, since each satellite data brings around the satellite in a sphere. You can limit the considerations down to a single point by programming the crossings. The collision of three satellites positions you on two possible points. The last satellite shows you exactly where you are.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
