Explanation
Statement 1 is incorrect: jet streams are high-altitude westerly (not easterly) winds in the mid-latitudes — the subtropical and polar-front jets blow from west to east. Statement 2 is correct: El Niño is a warm ocean current/warm-water anomaly. Statement 3 is correct: it appears periodically off the Peru–Ecuador coast in the eastern Pacific, disrupting fisheries and weather. Therefore only statements 2 and 3 are correct — option B.
