Answer: C) Raja.
Step-by-step explanation: a pronoun is a word that can function as a noun phrase used by itself and that refers either to the participants in the discourse or to someone or something mentioned elsewhere in the discourse. In the given sentence we can see an example of a possessive pronoun (it indicates belonging) in the word "his," the antecedent of this pronoun is "Raja" because the money belongs to him. So the correct answer is option C.
