Understanding the question took much more than solving it...

Even after the clarification, overlapping condition of 3 candles has two different meaning hence two different answers are available. Consider A, B and C as candles, Does the case that “A” overlaps with “B” but none of them overlaps with “C”, satisfy the overlaping condition?
