When faced with conflicting desires needs or values what type of conflict may you experience when you have to select from two favorable outcomes?

The answer would be approach-approach conflict.
For this type of conflict, you wouldn't face any negative consequences for your choices and the conflict happen because you're not sure which one would give you more positive consequences.
Example, when you only have enough money to buy one ice cream, but you couldn't decide whether to choose vanilla or chocolate flavour.
