The correct answer is C) Both longitude and latitude of the place.

To precisely locate any point on the Earth’s surface on a 2D map, you need a system of coordinates. The most common system uses latitude and longitude. Latitude measures the angular distance north or south of the equator, and longitude measures the angular distance east or west of the Prime Meridian. The intersection of a specific latitude and a specific longitude provides a unique location on the map. Altitude (height above sea level) describes the vertical position and is not needed to locate a point horizontally on a standard map.

Latitude lines (parallels) run horizontally around the globe, parallel to the equator. Longitude lines (meridians) run vertically from the North Pole to the South Pole. Together, they form a grid system allowing for the precise identification of any location on Earth. GPS devices use latitude, longitude, and altitude data to determine a user’s position. However, for locating a place on a map, only latitude and longitude are required for the horizontal coordinates.
