The question is asking for the three lewis structures for c3h4. I did one with a triple bond between the central carbon atom and another carbon atom and I did a structure with the central carbon double bonded to two other carbon atoms. I cannot figure out what the third one could be so if anyone has any idea let me know.

The third one you can create a triangle ring between all the carbons and have the hydrogen stick out of them. Sorry for not explaining it so well, but I hope it helps.

The third one is cyclic

For the last structure, bond the carbons together in a sort of circle/triangle shape. Then bond the Hydrogens to the carbons, on the outside of the circle.

What others have said about triangular/cyclic shape is correct.
