Which of the following supports the theory of continental drift?

the depth of the oceans
the climate of the south american continent
the size of glaciers in alaska
the fossil record

I very much believe your answer is D). The Fossil Record.  Because from what I know some dinosaurs of the same species are found on different continents.  They couldn't swim which might prove continental drift.

The depth of the oceans support this theory.

That is true , instead try to have a sit down talk with them
