The fragment that is made up of a complete predicate is option A. "could not be heard above the voices in the hallway"
In grammar, the predicate is defined as the part of the sentence that contains the verb and gives information about the subject.
Option A is the only option that contains a verb, in this case "could" and it is providing information about a subject we don´t know. The only options lack verbs,

The destruction of any public property, be it statues or historical buildings, is completely unjustifiable. Not only does destroying these artifacts not benefit anyone, but it hurts countless people. From public workers, who'd have to either rebuild or clean up the destroyed property, to people with connections to the monuments having to deal with the losses, no one is benefited by blatant acts of destruction such as these. And, arguably, not even those who commit them.
