What is temperature? a measure of the kinetic energy of a system. energy of a system. how hot something is. a measure of density.

Option (a) is the correct answer.

Explanation:

Kinetic energy is defined as the energy obtained by an object because of its motion.

When we measure this kinetic energy of an object or system then it is known as temperature.

For example, if temperature of a system is 89 degree celsius then it means measure of kinetic energy of this system is 89 degrees.

Hence, we can conclude that a measure of the kinetic energy of a system is called temperature.

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
