How have atmospheric carbon levels changed? without any fossil fuel consumption, which parts of the cycle have improved their carbon levels in comparison to previous data? which sections of the cycle have improved from the previous levels you have recorded but still are increasing their carbon levels?

im pretty sure its b

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
