When Learning About Light, We Predicted That Venus Should Have

When learning about light, we predicted that Venus should have a temperature of 230 K based on its albedo and distance from the Sun.Why is Venus's observed average surface temperature equal to 740 K, which is hot enough to melt lead?

A) Venus has slow retrograde rotation, and its seasons are very long.
B) Venus has many active volcanoes that release heat into its atmosphere.
C) Venus has a very thin atmosphere, and so more sunlight falls onto its surface.
D) Venus has a strong greenhouse effect.
E) Venus has a highly eccentric orbit and is sometimes much closer to the Sun than other times.
