Where (in relation to the sun) are the four densest planets? A) farthest from the sun B) nearest to the sun C) distance from the sun is not related to density D) distance and density are in exact agreement

B) nearest to the sun

Explanation:

Density may be defined as the amount of matter a body contains. Mathematically, it is the ratio of the mass to the volume of space that it occupies. Density of an object will determine if the object sinks or it floats when the object is put into some liquid, such as water.  

In our solar system, the planets that are nearest to the sun are the terrestrial planets. They are composed of metals or mainly silicate rocks and they have a solid surface. They are Mercury, Venus, Earth and Mars. Thus they are densest planet as compared to other planets which are mainly composed of gases like Jupiter, Saturn, etc.
