Three different samples were weighed Using a different type of balance for each sample. The three were found to have masses of 0.1900411 kg, 2.119 mg, and 4635.0 g. The total mass of the samples should be reported as

elements make up everything, and they combine to make compounds.

the answer is c

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.
