What is the compound with the formula C3P2?

I analyse the question and come to an answer using the method:

1) If counting the number of Carbons, we can count three which means it is a propane group.

2) If we count the number of carbon-to-carbon bonds initiated into the compound, we can count two double bonds which means the -ene suffix.Therefore i can say the formular C3H4 is called a Propene.
