The terrestrial planets are the planets, which are made up of heavy metals and rocks. These have a hard surface. These planets have molten metal core which is heavy. These planets have few moons and topological features such as volcanoes, craters and valleys.
All these terrestrial planets have typically the same type of structure that is the metallic core in the center that is composed of iron, and surrounded by the layer of silicate mantle.
Thus on the basis of the above description, the planets made of heavier elements is the correct option.
