To answer this question, we need to understand the context of the statement. According to Hindu mythology and the Mahabharata epic, Dronacharya was a renowned warrior and the royal teacher for the Pandavas and Kauravas.
The correct answer is option C) Dustadyumna. Dustadyumna was born specifically to kill Dronacharya. After Dronacharya killed Drupada's son in battle, Drupada performed a yagna (a ritual sacrifice) to obtain a son who would be capable of defeating Dronacharya. As a result, Dustadyumna was born from the yagna and later accomplished his purpose by killing Dronacharya during the Kurukshetra war.
