Ethanol on treatment with concentrated HI and red phosphorus forms

This reaction is ,

$\underset{\mathrm{Ethyl} \mathrm{alcohol}}{{\mathrm{CH}}_3{\mathrm{CH}}_2-\mathrm{OH}+2\mathrm{HI}}\stackrel{\mathrm{Red}\mathrm{P}}{⟶}\underset{\mathrm{Ethane} }{{\mathrm{CH}}_3-{\mathrm{CH}}_3+{\mathrm{H}}_2\mathrm{O}+{\mathrm{I}}_2}$

Thus the correct option is C
