Answer:
Point A - Intrusive igneous rock
Point B - Extrusive igneous rock 
Explanation:
Intrusive igneous rocks are rocks which is formed by molten magma that cools and solidifies below and within the surface of the earth, thereby forming large crystals beneath the earth surface. Examples of Instrusive igneous rocks gabbro, granite, peridotite etc.
Intrusive Ignoeus rock is formed at point A in the diagram given above.
Extrusive Ignoeus rock, on the other hand, is the opposite of Intrusive igneous rock. Extrusive igneous rock is formed when molten rocks, called magma, erupts from beneath the earth and cools and solidifies on the surface of the earth, thereby forming small crystallized rocks. Examples of extrusive igneous rocks are basalt, pumice, etc.
Extrusive Ignoeus rocks would formed at point B in the diagram above.

Answer:
C: Fire
Explanation:
Natural and anthropogenic (caused by human) fires could lead to destruction of existing climax community. This leaves the habitat open for the secondary succession where a pioneer species can enter. Lava flow and wind are the natural cause of succession while over-cutting of trees is its human cause.
