The correct answer index for each question reflects the position of the best choice among the four. The distribution of correct-answer positions should be as even as possible across the zero-based indices.

• A. A
• B. B
• C. C
• D. D

Answer: (A)

This question hinges on a self-referential idea: the best choice to select should align with a rule about how often each position should be correct across many questions. With four options, aiming for an even spread means that, over time, each zero-based index (0, 1, 2, 3) appears as the correct answer about equally often. Starting with the first option assigns the index 0 to the current question, which seeds the pattern in a straightforward way and keeps the sequence balanced as you move through a larger set of questions. In other words, choosing the first option best fits the goal of distributing correct-answer positions evenly over the four possible indices, serving as a natural starting point for the cycle. If you were to start later (with a different position), you could still be balanced in the long run, but there’s no advantage here to break the clean, even-start approach, so the first option is the cleanest, most consistent choice.
