Answer : 2. "Greenland and Canada"
Explanation :

A microcontinent has been discovered in the Davis Strait, between Canada and Greenland. Formed millions of years ago due to tectonic plate shifts, it features a 19–24 km thick continental crust, now named the Davis Strait proto-microcontinent. The strait, spanning 650 km north to south and 200-400 miles wide, connects the Atlantic and Pacific Oceans via the Northwest Passage, but is impassable in winter due to ice.
