The correct answer is option 1: Bass. The Bass Strait is a narrow stretch of water that separates mainland Australia from the island of Tasmania. It is located in the southern part of the Indian Ocean, and it is approximately 240 km wide at its widest point. The strait was named after George Bass, a British explorer, who first sailed through it in 1798. The Bass Strait is an important shipping route and has played a significant role in the history of Australia, particularly in terms of colonization and trade between the mainland and Tasmania. It is also known for its challenging maritime conditions, with strong currents and rough seas, making it a crucial navigational area for shipping vessels.
