Welllll, that's the correct choice alright, but the question is awful.
Real scientists do NOT dream up a theory and then go looking for evidence to support it. What they do is exactly the opposite.
Real scientists gather observations of nature and how things work. Eventually, they propose a theory to explain how it all fits together.
Wegener OBSERVED coastline fit, and he OBSERVED similar rocks and fossils on different continents. Eventually, he OBSERVED so many examples that he said to himself "Self ! This can't all be just a bunch of coincidences ! There HAS to be some kind of mechanism behind it.", and he constructed and published his theory of continental drift.
Evidence is not USED to support a theory. A theory is OFFERED to explain evidence, and then it's tested to determine whether it holds water, or whether we've just been fooling ourselves.
