In Chapter 12 You Used E^o to Predict When a Redox

In chapter 12 you used E^o to predict when a redox reaction would be spontaneous. In chapter 13 $\Delta$ G^o was used to predict if a reaction was spontaneous. Which of the following describes the relationship between $\Delta$ G^o and E^o?

A) when $\Delta$ G^o is positive, E^o is negative
B) when $\Delta$ G^o is positive, E^o is positive
C) when $\Delta$ G^o is negative, E^o is negative
D) when $\Delta$ G^o is negative, E^o is zero
E) There is no relationship between $\Delta$ G^o and E^o.
