a how plates move
b. where fossils were found
c. evidence of glaciers

Explanation:

Wegener's Continental Drift Theory proposed that continents move, but initially lacked a mechanism (how plates move). Plate tectonics later provided this. Fossil distribution (B) and glacier evidence (C) were actually used as supporting evidence. What plates are made of (D) wasn't the key missing part.
