The answer is four. The law of conservation of mass basically says that whatever is but in will always have the same mass coming out. so for example if you had 10 grams of water and then you heated it up, it is still 10 grams of water.
I think you forgot to include the picture so that we could easily identify the bond. No matter, I can introduce the types of bonds involved in chemistry. There are only two: the sigma bond (first picture) and the pi bond (second picture).
The sigma bond is formed when the two electrons sharing an orbital are overlapped head-on. In other words, they overlap each other entirely. While a pi bond is a side-to-side overlapping kind of sharing. That is why sigma bonds are much stronger than pi bonds.
In this case, just please refer to the picture for you to identify which type of bond is it indicated in your homework.
