Plasma is often in stars, which are likely to contain?

Below are the choices that can be found from other sources:

A) elements 
B) ions 
C) molecules 
D) neutrons

the answer is ions. 

A Star and hence our Sun, is an almost entirely ionized ball of plasma, consisting of electrons and ions, in which there is hardly any gas (neutral atoms). The movement of the plasma produces strong magnetic fields and corresponding electric currents.

I’d have to say no because without oxygen in the water the fish would all be dead. so if you want to fish for dead fish, pick the ponds with the lowest oxygen concentrations.
