Which of the following pairs are correctly matched ? 1. Yangtze Kiang : East China Sea 2. Euphrates : Aral Sea 3. Lena : Arctic Ocean 4. Mekong : Japan Sea Select the correct answer using the codes given below:

The Yangtze River (Chang Jiang), the longest river in Asia, originates in the Tibetan Plateau and flows eastward to drain into the East China Sea [1][t1]. The Lena River is one of the major high-latitude rivers of Russia that flows northward across Siberia to empty into the Arctic Ocean [t2]. In contrast, the Euphrates River flows through Turkey, Syria, and Iraq to join the Tigris and eventually drain into the Persian Gulf, not the landlocked Aral Sea [t3]. The Mekong River flows through Southeast Asia and empties into the South China Sea, specifically through the Mekong Delta in Vietnam, rather than the Japan Sea [c1][t6]. Therefore, only pairs 1 and 3 are correctly matched regarding their respective river outlets.
