Why might a country attempt to hide an outbreak of an infectious Disease?A. For political reasons B. To avoid disruption to trad C. To avoid disruption to travel D. To stop scientists from finding a cure or vaccine

B (not 100% sure, my bad if thats wrong).

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.
