In ethyne, the two carbon atoms contain:

Aone sigma bond and two pi bonds
Correct Answer
Bone sigma bond and one pi bond
Ctwo sigma bonds and one pi bond
Dtwo sigma bonds and no pi bond

Solution

The structure of ethyne: $$H-C\equiv C-H$$

The triple bond between two carbon atoms has one $$\sigma$$ bond and two $$\pi$$ bonds.

So, the correct option is $$A$$
