C. English Channel of UK
D. Hudson River of North America
🧠 Explanation:
The English Channel, located between southern England and northern France, is considered the world’s most challenging long-distance swimming course. It stretches about 34 kilometers at its narrowest point but can feel much longer due to strong tides, cold water, and unpredictable weather. Swimmers often face jellyfish, shipping traffic, and exhaustion during the attempt. Successfully crossing the Channel is seen as one of the greatest achievements in open-water swimming. It represents endurance, courage, and determination.
