A

Cu2OCu_{2}O

B

[Cu(NH3)4]SO4\lbrack Cu(NH_{3})_{4}\rbrack SO_{4}

C

[Cu(NH3)4]OH\lbrack Cu(NH_{3})_{4}\rbrack OH

D

[Cu(H2O)4]SO4\lbrack Cu(H_{2}O)_{4}\rbrack SO_{4}

Answer

[Cu(NH3)4]SO4\lbrack Cu(NH_{3})_{4}\rbrack SO_{4}

Explanation

Solution

CuSO4+4NH3→[Cu(NH3)4]SO4CuSO_{4} + 4NH_{3} \rightarrow \lbrack Cu(NH_{3})_{4}\rbrack SO_{4}
