Why is the provence called bc?

The province of British Columbia (BC) is named for the Columbia River, which was named by Captain Robert Gray in the late 18th century. The name "Columbia" itself is derived from Christopher Columbus, reflecting the era of exploration and colonization. When the region became a British colony in the 19th century, it was designated as British Columbia to emphasize its colonial ties to Britain and its geographical location on the west coast of North America.
