An antecedent of a pronoun is a word that refers to the same thing as this pronoun.
here the pronoun is "theirs"
<em>Rivers stopped flowing along the bank's so that they could hear Orpheus, whose music was harmonious than </em><em>theirs.</em>
(all the words in Boldface refer to the same thing).
What does the "theirs" refer to? it refers to their music, and the they is the Rivers (it's a personification of rivers)
The antecedent is the river!
I'd have to say D is the correct one.
A robbery was committed at the local art gallery in Newtown at 1 o'clock this morning. It is believed that three men were involved. It was reported that two paintings were stolen. The curator and some witnesses were interviewed by the police since this morning. No one was caught yet. The paintings were donated to the gallery by Mr. Harris when the gallery opened two years ago. It is hoped that the robbers are caught soon.
