How does a coronal mass ejection (CME) affect the solar wind?

A CME adds more particles to the solar wind, intensifying it.

A CME does not affect the solar wind but it does affect auroras.

A CME blocks the solar wind, causing it to fade.

A CME increases the amount of energy in the solar wind.

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
