Answer to Question 1

B

Answer to Question 2

There are hundreds of volcanoes on the surface of Venus. Atmospheric chemistry has shown levels of sulfur dioxide that show large and frequent fluctuations, which could be produced by active volcanism. Bursts of radio radiation similar to those from volcanic eruptions on Earth have also been observed. Venus Express has also mapped areas that are warmer, indicative of volcanism in the comparatively recent past.
