How Are Spicules Formed in the Sun's Chromosphere

How are spicules formed in the Sun's chromosphere?

A) Spicules are formed from material on the tops of granules "tossed" to higher altitudes by the oscillations of the Sun's surface.
B) Spicules are formed from plasma carried upward along with the magnetic field lines at the edges of supergranules.
C) Spicules form where the Sun's twisted magnetic field lines break through the photosphere.
D) Spicules are the remnants or "stumps" of solar prominences that have broken free of the magnetic fields that confine them and have erupted out into space.
