As per Continental Drift Theory, Earth's present-day continents were once a single, giant landmass. What is the name given to this super continent?

Pangaea

The correct answer is Option (1) - Pangaea

In 1912, German scientist Alfred Wegener proposed a theory he called continental drift. According to Wegener's theory, Earth's continents once formed a single, giant landmass, which he called Pangaea. Over millions of years, Pangaea slowly broke apart, eventually forming the continents as they are today.
