From the following languages listed in the Eighth Schedule of the Constitution pick out of the one which is the official language of a State?

The Eighth Schedule of the Indian Constitution lists 22 languages, including Kashmiri, Urdu, Sindhi, and Nepali [t1][t7]. Among the options provided, Urdu is a prominent official language of a State. Historically, Urdu was the sole official language of the state of Jammu and Kashmir [c4]. Following the Jammu and Kashmir Official Languages Act, 2020, it remains one of the five official languages of the Union Territory [c1]. While Nepali is an official language in the state of Sikkim [t4], and Kashmiri was recently granted official status in the UT of Jammu and Kashmir [t4], Urdu has long held the status of a primary official state language in the Indian constitutional framework. Sindhi, although a scheduled language, does not serve as the official language of any specific Indian state [c4]. Therefore, Urdu is the most established answer in the context of traditional state official language designations.
