Prominences and flares on the sun can best be described as
a. electrically charged particles
c. cooler areas on the sun
b. the effect of earth’s gravitational pull on the sun
d. auroras

a. electrically charged particles

Explanation:

Surface of sun is made up of gases like hydrogen and helium

Now due to high temperature of sun the hydrogen gas nuclei has tendency to combine and give nuclear fusion reaction.

Due to this nuclear fusion of gas molecules it releases large amount of energy which will release large amount of accelerated charge particles. This large number of charge particles is known as Solar flare or Prominences.

These solar flares moves out at high kinetic energy and travels in all random directions

So here correct answer will be

a. electrically charged particles
