    Answer : Option D

    Explanation :

    Rocks which are formed by the solidification of lava on the earth's surface are Basalts. Basalt is a dark-colored, fine-grained, igneous rock composed mainly of plagioclase and pyroxene minerals. It most commonly forms as an extrusive rock, such as a lava flow, but can also form in small intrusive bodies, such as an igneous dike or a thin sill.
