Ionophores have following action except: (A) Abolish proton gradient, (B) Inhibit ADP to ATP conversion, (C) Hydrophilic in character, (D) Abolish pH gradient
Answer is C. Hydrophilic in character 

Inophors are lipophilic (not hydrophilic).
Inophors inhibit ATP formation by inhibiting oxidative phosphorylation by abolishing proton gradient or pH gradient.
