The correct equation for the reaction of dimethylamine with hydrochloric acid is (CH3)2NH + HCl → (CH3)2NH2+Cl-. This can be represented with the following ionic equation: (CH3)2NH + H+ + Cl- → (CH3)2NH2+Cl-. 
Option C is the correct representation of this ionic equation, with (CH3)2NHSO4- as the spectator ion. The other options either have incorrect products, incorrect coefficients, or both.
