Let’s calculate the total elevation change:

-280 + 350 - 620 + 100 - 400 = -850.

Since the race started 850 meters above Town X, a net drop of 850 meters means it ended at the same elevation as Town X.

Answer: B.

This is a simple arithmetic problem, as easy as it gets. Just add and subtract the elevation changes step by step. Nothing fancy, just careful calculation.
