Thank you! :D Can you please explain why? :)

OpenStudy (rina.r):

There is a double bond between the two carbons, so that is one sigma bond and one pi bond. The hydrogen's all are sigma bonded to the carbons so there are four sigma bonds there. So, there is one pi bond overall and five sigma bonds overall.
