The term refers to one landmass made up of all the modern contents.
a) subcontinent
b) arctic
c) super continent
d) tectonic

It would be super continent since the arctic is a region, tectonic is the plates that move the continents, and subcontinent is one specific continent, such as North America and South America. Super continent is when all the continents were connected as one huge continent.

I believe the correct answer from the choices listed above is option C. The term super continent refers to one landmass made up of all the modern contents. It is the assembly of most or all of Earth's continental blocks or cratons to form a single large landmass. Hope this helps.
