Given: \( \mathrm{E}_{\mathrm{Ag}^{+} / \mathrm{Ag}}^{0}=+0.8 \mathrm{~V} ; \mathrm{E}_{\mathrm{Ni}^{+} / \mathrm{Ni}}^{0}=-0.25 \mathrm{~V} \). Which of the following statements is true?
(a) \( \mathrm{Ag}^{+} \)is an oxidizing agent but \( \mathrm{Ni}^{+2} \) is a reducing agent
(b) \( \mathrm{Ni}^{+2} \) can be reduced by silver metal
(c) \( \mathrm{Ag}^{+} \)is a better oxidizing agent than \( \mathrm{Ni}^{2+} \) and \( \mathrm{Ni} \) is a better reducing agent than \( \mathrm{Ag} \)
(d) \( \mathrm{Ni}^{+2} \) is a better oxidizing agent than \( \mathrm{Ag}^{+} \)and \( \mathrm{Ag} \) is a better reducing agent than \( \mathrm{Ni} \)
