Which of the following is most likely to be found in the St. Lawrence Seaway?

The St. Lawrence Seaway is a system of locks, canals, and channels that allows ships to transit between the Atlantic Ocean and the Great Lakes, including Lake Ontario. Among the options provided, Melville Shoal is a specific geological feature located within the St. Lawrence River, which is part of the Seaway. It is significant for navigation and maritime activities in that area.

The Erie Canal, while an important waterway, is separate from the St. Lawrence Seaway and connects the Hudson River to Lake Erie. Nanticoke Creek is a smaller localized waterway and does not connect to the broader system of the St. Lawrence Seaway. Lake Simcoe, although a significant lake in Ontario, is also not part of the St. Lawrence Seaway, as it does not directly feed into the Great Lakes or the Seaway system.

Understanding these geographical distinctions helps clarify why Melville Shoal is the correct choice, as it directly relates to the navigation and features found within the St. Lawrence Seaway.
