Liquid water (H2O) is formed when two gases, hydrogen (H2) and oxygen (O2), react. Why are the properties of water different than those of the
reactant gases?
Select one:
Water wil retain some of the properties of hydrogen as there are more hydrogen
atoms in water than oxygen atoms.
When substances chemically combine, products with completely different properties
form.
The properties of the two gases are combined to give water its properties.
Water has similar properties to either hydrogen or oxygen gases.

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.

c) should be the answer.
