Correct answer
Explanation
When something is "up in the air," it means it's uncertain, unresolved, or not yet decided - similar to how something floating in the air could go in any direction. This idiom describes plans, decisions, or situations where the outcome isn't known yet. Option B correctly identifies this as meaning undecided.
