The lone pairs in a water molecule cause it to have which shape?

A 104 degree bond angle, or a V shape

Lone pairs in a water molecule cause it to have non linear shape (angular or bent shape)

The lone pairs of water molecules repel each other in a way that water molecules get angular shape instead of linear shape.

Angular molecules (also called bent or V-shaped) have a non-linear shape. For example, water (H2O), which has an angle of about 105°. A water molecule has two pairs of bonded electrons and two unshared lone pairs.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

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.
