The answer: E. sp²
The structural formula of C₂H₂ is shown below.
There are 4 valence orbitals, i.e. one 2s and three 2p, in each carbon atom in C₂H₂.
The 2s orbital and two 2p orbital hybridize to give three sp² orbitals and one 2p orbital is left unhybridized.
The three sp² orbitals form one C-C σ bond and two C-H σ bonds.
The unhybridized 2p orbital forms one C-C π bond.
