Answer: Option (D) is the correct answer.

Step-by-step explanation:

General formula of an alkyne is
C_(n)H_(2n-2).

Suffix "yne" in the name of a compound represents that there is a triple bond present in the compound.

So, a molecule of propyne will have three carbon atoms, four hydrogen atoms and a triple bond. Therefore, there wll be 6 sigma bonds and 2 pi bonds in a propyne molecule.
