Answer:
I believe it's opportunity cost - (D)
Explanation: I think this because the exact definition of opportunity cost is - "The loss of potential gain from other alternatives when one alternative is chosen" which fit's perfect in this scenario here's an EX. you want to go to the movies that's your first option your second option is to go to an arcade but you don't so that experience you could've had you didn't is called opportunity cost which is what this question is referring to. Hope this helps have a good day!
