Option 1 -> "Concurrent" means happening at the same time, which doesn't apply to championships held in different seasons.
Option 2 -> "Cumulative" means accumulated over time, but doesn't emphasize the unbroken sequence that makes a record.
Option 3 -> "Consecutive" means following one after another without interruption, which describes winning championships in successive seasons.
Option 4 -> "Consequential" means important or significant, but doesn't describe the nature of the achievement itself.
Hence, Option 3: consecutive -> Winning three championships in a row (one after another without any interruption) is what creates a remarkable record in sports history. This unbroken sequence of victories is what makes the achievement record-worthy. -> correct
