b-venus
Venus has a dense atmosphere, composed chiefly of carbon dioxide, which generates a surface pressure 90 times greater than that on Earth. This massive blanket of carbon dioxide is also responsible for a runaway greenhouse effect that heats the planet's surface to an average temperature of 467°C (872°F) – hot enough to melt lead.
Venus' atmosphere consists almost entirely (97%) of carbon dioxide, with clouds containing droplets of sulfuric acid along with compounds of chlorine and fluorine. These precipitate an acid rain called virga, which evaporates before it has the chance to reach the surface. In the upper part of the atmosphere, clouds swirl by at a rate of 300 km/h, driven by fierce winds.

Venus is way hotter because it has an rather thick ecosystem of sulfuric acid which does no longer allow the warm temperature get away. Mercury can get to -2 hundred levels at the same time as no longer dealing with the solar because it does no longer have a thick ecosystem.

venus,, venus is a very hot and hostile place with sulpheric acid in its atmosphere,,
just for fun here is some pics of the surface of venus from the russian ships venera 13 and venera 14,, they took pictures for about 50 minutes before burning up and being crushed,,
