Final answer:
A triple bond is characterized by being the strongest type of covalent bond, formed by three pairs of electrons shared between two atoms, resulting in a bond that is both shorter and stronger compared to single or double bonds.
Step-by-step explanation:
The characteristics of a triple bond are outlined by option C, which is the strongest type of covalent bond with three bonds holding two atoms together. This type of bond involves the sharing of three pairs of electrons between two atoms, significantly increasing the bond strength as compared to single and double bonds. The triple bond is exemplified in molecules like nitrogen (N₂), where each nitrogen atom shares three electrons forming a very stable bond. As more electron pairs are shared, the bonds become shorter and stronger, which is why triple bonds are the shortest and strongest among covalent bonds.
