The correct answer is C. Rajendra I (Chola). Rajendra Chola I, son of Rajaraja Chola I, led a famous naval expedition against the Srivijaya kingdom around 1025 CE. Srivijaya was a powerful maritime empire controlling the Malay Peninsula, Sumatra, Java, and nearby islands. Rajendra I’s campaign asserted Chola naval dominance in the region and secured control over important sea trade routes. The other rulers listed did not conduct campaigns against Srivijaya: * Amoghavarsha (Rashtrakuta) focused mainly on the Deccan region.
* Prataparudra (Kakatiya) ruled much later and was centered in the Deccan.
* Vishnuvardhana (Hoysala) focused on South Indian affairs.
