Your Friend Is Having a Little Difficulty Understanding the Nature

Your friend is having a little difficulty understanding the nature of covalent bonding,especially single bonds,double bonds,and triple bonds.He thinks that you can explain the difference.What answer would be correct?

A) Covalent bonds are bonds between atoms in which the atoms share electrons.For example,a single bond involves one electron,a double bond involves two electrons,and a triple bond involves three electrons.
B) Covalent bonds are bonds between atoms in which the atoms shares pairs of electrons.For example,a single bond involves one pair of electrons,a double bond involves two pairs of electrons,and a triple bond involves three pairs of electrons.
C) Covalent bonds are bonds between atoms in which the atoms receive electrons.For example,a single bond involves removing one electron,a double bond involves removing two electrons,and a triple bond involves removing three electrons.
D) Covalent bonds are bonds between atoms with polar sides.For example,a single bond involves one electron and one proton,a double bond involves two electrons and two protons,and a triple bond involves three electrons and three protons.
