What Are the Energetic Consequences of Coupling a Reaction with a

What are the energetic consequences of coupling a reaction with a + $\Delta$ G to one with a larger - $\Delta$ G?

A) An outcome in which the overall $\Delta$ G is positive
B) An outcome in which both reactions are energetically unfavorable overall
C) A $\Delta$ G that is favorable overall and drives the reaction with a + $\Delta$ G in the forward direction
D) An outcome in which the overall $\Delta$ G is unfavorable
