The Ganga-Brahmaputra river system forms the world's largest delta, known as the Sundarbans Delta, at its mouth in West Bengal and Bangladesh. This massive delta, covering about 80,000 square kilometers, is formed by the deposition of sediments carried by both rivers as they approach the Bay of Bengal. The delta is famous for its mangrove forests and is home to the Royal Bengal Tiger.
Final Answer: Option A - Ganga-Brahmaputra
