Hydroxyapatite, [Ca₅(PO₄)₃(OH)], the Major Component of Tooth Enamel, Is Attacked $\rightarrow$

Hydroxyapatite, [Ca₅(PO₄) ₃(OH) ], the major component of tooth enamel, is attacked and decomposed by acids more readily than fluorapatite, [Ca₅(PO₄) ₃F]. Which one of the following reactions is analogous to the reaction of hydroxyapatite?

A) Ca(s) + 2HCl(aq) $\rightarrow$ CaCl₂(s) + 2H⁺
B) CaF₂(s) + 2H⁺(aq) $\rightarrow$ Ca²⁺(aq) + 2HF(aq)
C) Ca(OH) ₂(s) + 2H⁺(aq) $\rightarrow$ Ca²⁺(aq) + 2H₂O( )
D) Ca(s) + 2H⁺(aq) $\rightarrow$ Ca²⁺(aq) + H₂(g)
E) Ca₃(PO₄) ₂(s) + 6H⁺(aq) $\rightarrow$ 3Ca²⁺(aq) + 2H₃PO₄(aq)
