Water Isn't the Only Material to Undergo Ionization and Recombination

Water isn't the only material to undergo ionization and recombination with itself. Under special conditions, typically nonaqueous conditions, other materials can 'self-ionize'. What would be the self ionization products of liquid hydrochloric acid?

A) H₂ and Cl₂
B) H₂O and HCl
C) H⁺ and Cl^-
