El Niño occurs when the tropical eastern Pacific Ocean's surface waters are warmer than usual.

Explanation:
El Niño is defined by unusually warm sea-surface temperatures in the tropical eastern Pacific. That warming disrupts normal trade winds and atmospheric circulation, leading to characteristic global weather changes. So the statement is true: El Niño occurs when those eastern Pacific surface waters are warmer than average. The other options don’t fit the standard definition—it isn’t simply uncertain or occasionally true; El Niño specifically refers to that warming event in the eastern Pacific.
