It was about dusk, one evening during the supreme madness of the carnival season, that I encountered my friend. He accosted me with excessive warmth, for he had been drinking much. The man wore motley. He had on a tight-fitting parti-striped dress, and his head was surmounted by the conical cap and bells. I was so pleased to see him that I thought I should never have done wringing his hand.

In the excerpt above, the word surmounted most nearly means _____.
a) mounted upon
b)gotten over or across
c)prevailed over
d)equaled in value
