What is the name of the type of basaltic crust that moves under less dense crust? a. oceanic b. igneous c. continental d. asthenosphere

Oceanic

Explanation:

Oceanic type of basaltic crust moves under less dense crust. Oceanic crust density increases because of volcanic eruption that leads to formation of igneous rocks( when lava is cooled down to magma and it is further cooled to form igneous rocks) these rocks being heavier move downward under the less dense crust.
