You Had a Long Day at Work, Where You Were

You had a long day at work, where you were involved in three different meetings that were focused on problem solving. You also had to reprimand someone and put that person on progressive discipline. When you get home, your spouse asks you where you want to go to dinner. You say, "I don't care. You choose." This is most likely because

A) you really don't care
B) your spouse never listens to your suggestion
C) you're too tired to think about it
D) you're decision-fatigued
