Which statement best explains the process occurring in step 2 of the diagram?
A. Fertilized eggs are laid on water plants or released into water.
B. Egg cells are fertilized inside the female's body.
C. A zygote develops into an embryo inside each fertilized egg.
D. A nymph emerges from a fertilized egg and changes into an adult.

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.

it's c (engineer's do their work with mechanical stuff not on any living being)
