What was the term used by contemporaries for the Vijayanagara Empire?

Karnataka Samrajyamu

The correct answer is Option (1) → Karnataka Samrajyamu

The term "Karnataka Samrajyamu" was used by contemporaries for the Vijayanagara Empire because it referred to the fact that the empire was primarily located in the Deccan region of South India, with its capital, Vijayanagara, situated in present-day Karnataka.

"Karnataka" refers to the region, and "Samrajyamu" means empire, so "Karnataka Samrajyamu" can be translated as the "Karnataka Empire." This name reflects the geographic and cultural context of the empire and its rule over the Karnataka region.

So, the correct option is [1].
