The second option.

Comparative advantage depends on differences in opportunity cost, not absolute output. In the second scenario both countries make the same number of tablets, but Country A could instead make more laptops with those factories — so A has a lower opportunity cost (comparative advantage) in laptops and B has the comparative advantage in tablets. The other options describe absolute advantage or actions without information on opportunity costs.
