A
lava is magma but it is on the surface of the Earth
B
lava is the chamber that magma flows
C
lava is the Earth’s crust
D
None of the above
Explanation: 

Detailed explanation-1: -Scientists use the term magma for molten rock that is underground and lava for molten rock that breaks through the Earth’s surface.

Detailed explanation-2: -When geologists refer to magma, they’re talking about molten rock that’s still trapped underground. If this molten rock makes it to the surface and keeps flowing like a liquid, it’s called lava. Magmas vary in their chemical composition, which gives them-and the volcanoes that contain them-different properties.

Detailed explanation-3: -The molten rock that is present beneath the surface of the earth is termed as Magma. The molten liquid that gets erupted out of the surface of the Earth is termed as lava.

Detailed explanation-4: -The main difference between magma and lava is that when this molten rock is within the Earth, it is known as magma but when magma reaches the surface and erupts from a volcano, it becomes lava.

Detailed explanation-5: -Magma comes from an Italian word that means a thick, pasty substance, which is how molten rock behaves within the Earth. Lava, another Italian word, means to slide, which is what molten rock does once it reaches the surface.
