Solution

The correct option is A 4
Carbon contains four electrons in its valence shell. One carbon can share its valence electrons with other elements or with another carbon to form the covalent bonds.
Ethyne has a triple bond between the two carbon atoms as shown in the figure.
So, each carbon atom is having four covalent bonds in it.
