B. `H_(2)O+CH_(3)COOH hArr CH_(3)COO^(-) +H_(2)O^(+)`
C. `4NH_(3)+Cu^(2+) hArr [Cu(NH_(3))_(4)]^(2+)`
D. `HCl+CH_(3)COOH hArr CH_(3)COO^(+)H_(2)+Cl^(-)`

Correct Answer - C
In (C ) `NH_(3)` is donor and `Cu^(2+)` ion is acceptor. Hence, `NH_(3)` is base and `Cu^(2+)` ion is Lewis acid. `Cu^(2+)` is not acid according to Bronsted concept because it is not a proton donor.
