Is this a trick question? C3H2 doesn't exist. If you consider the 4 bonds that carbon usually makes, the bonds are usually arranged (for 4 single bonds) at bond angles like a tetrahedron. If you have a triple bond, the total bond angle across the carbon atom is 180 degrees. Too much bond stress is required to "bend" these bonds to the 60 degrees required to form cyclopropyne.
