An atom is much more stable with 2 electrons in its first shell. Hydrogen has only 1 electron, so two atoms of hydrogen combine to form a H2 molecule, which enables each of them to share electrons. This allows them to behave as if they each had 2 electrons in the shell.
Atoms undergo chemical bonding in order to achieve stable valence shells. In order for oxygen atoms to accomplish this when they bond together, they share two pairs of valence electrons, which is a double bond.
This question seems a bit unclear. Perhaps it meant something like: "how many electrons can be shared with carbon atoms?" Anyway, a carbon atom can share 4 electrons with other atoms, including other carbon atoms.
Carbon and silicon are two elements that share four electrons while bonding. Occasionally, in compounds like sulfur tetraoxide, elements other than in group 14 also share exactly four electrons.
The answer is c. Valence electrons are shared between oxygen atoms & D. Four valence eletrons are shared
each oxygen shares two electrons, resulting in 4 electrons shared
a carbon atom can share electrons with up to four other atoms.

The chlorine atoms share two electrons between themselves, while the oxygen atoms share four. This can alternatively be stated as a single bond between the two chlorine atoms and a double bond between the two oxygen atoms.

One carbon atom will typically share electrons with four other atoms to complete its outer electron shell, achieving a stable configuration. This enables it to form up to four covalent bonds with other atoms.
each oxygen shares two electrons, resulting in 4 electrons shared
Oxygen has 6 electrons in the outer shell. A full shell needs 8 electrons. Each atom therefore needs to 'borrow' 2 electrons from the other. You could therefore consider that 4 electrons are shared in the molecule (each borrows 2 of the others electrons).

Atoms are always trying to get a full valence shell (outer shell of electrons) to make themselves stable. Hydrogen and Helium only need two electrons to do this, but the other elements need eight electrons in their valence shell. Atoms try to accomplish this in the easiest way possible, using single bonds. Sometimes, though, this doesn't work. A common example of double bonding is carbon dioxide. Carbon has four electrons in its valence shell and wants to have eight. That means it wants other atoms to share four electrons with it so it can fill its shell. The two oxygen atoms that it bonds to when it becomes carbon dioxide have six electrons in their valence shell and want eight. That means they want to share two electrons each with another atom so they can have eight electrons in their valence shell and be "full". The atoms work together, sharing electrons to fill each other's valence shells, and each of the two oxygens form a double bond with carbon. The carbon atom gets two electrons from each oxygen (four total) to add to its own four to make a total of eight electrons (a full valence shell). Each oxygen gets two electrons from the carbon atom to add to its own six, making a total of eight electrons (a full valence shell). Basically, atoms share more than one pair of electrons in double or triple bonds because it's the best way for them to fill their valence shell.
