Answer to Question 1

B

Answer to Question 2

Because of Venus' proximity to the Sun, carbon dioxide never got absorbed by surface rocks due to higher temperature. Carbon dioxide is a greenhouse gas and traps heat, so this led to still higher temperature, leading to even more carbon dioxide released from rocks in a vicious cycle. The result is a surface temperature of 730 K.
