Answer:
Option A
Explanation:
Corona is defined by the strong magnetic fields. When these strong magnetic fields confine solar atmosphere and produces violent bubble of gases then it is said to cause coronal mass ejection (CME).
When a CME passes through the solar wind, it causes production of high velocity solar energetic particles that follow magnetic field lines and passes through the space between the Sun and the Earth. The charged particle added by CME intensifies the solar wind.
Hence, option A is correct
Alternative energy sources are those that do not deplete natural resources and do not harm the environment.
Options A, B, and C are all fossil fuels, which we know can be depleted and harm the environment.
The only valid option here is D, Geothermal energy.
Geothermal energy is both renewable and environmentally friendly.

Explanation:
The difference between extrusive and intrusive rocks are how they cool
down. Extrusive rocks cool down quickly and are created by lava; because
of this they have very small, fine-grained crystals. Intrusive rocks
cool slowly beneath the surface of the earth and are created by magma;
because the cooling process is very slow the rocks have very large
crystals.
