The answer is C - the indirect object in this sentence is team. This is because when someone or something gets the direct object, they are the indirect object. For example, the sponsor bought the team new uniforms. The sponsor is the subject, and bought is the verb. What did the sponsor buy? New uniforms, which in this sentence is the direct object. Who got the uniform? The team = that makes team the indirect object in this sentence.
