Explanation:

In English language there are two voice: Active voice and Passive voice. Passive voice is used when we want to emphasize the action (the verb) and the object of a sentence rather than subject. That means in passive voice the subject holds less importance as compared to action. In the given sentence the main theme is to make clear about the winning goal. For example: I wrote the letter. (active voice) The letter was written by me. (passive voice)
