a.
nebulae
b.
prominences
c.
corona
d.
constellations

b.  prominence

Explanation:

Charged particles emit from the sun and arch up from the surface of the sun and extend into the corona. These are prominence which form loops. These are visible as dark filaments against bright surface of sun- photo-sphere. These release large amount of magnetic energy. These heat up  and accelerate the gas in sun's atmosphere.

Thus, Electrically charged flares that arch up from the Sun are known as prominence.

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.
