Explanations:In India, each state has an official language, which is often the predominant language spoken by the majority of the population within that state. The official language can play a significant role in the cultural and administrative identity of the state. However, the relationship between the state name and the official language varies from state to state.
For the question at hand, we are looking for a state where the name of the state includes the name of its official language. This is a unique characteristic that is not common among all Indian states. Let's examine each state mentioned in the options:
Tamil Nadu: The official language of Tamil Nadu is Tamil. The state name "Tamil Nadu" literally translates to "Land of Tamil" in English. This makes Tamil Nadu the only state in India where the name of the state includes the name of its official language. The term "Tamil" is a significant part of the state's identity and is reflected in its name.
Telangana: The official language of Telangana is Telugu. However, the state name "Telangana" does not include the name of the language. The name "Telangana" is derived from the Telangana region, which has historical and cultural significance, but it does not directly incorporate the name of the official language.
Karnataka: The official language of Karnataka is Kannada. The state name "Karnataka" does not include the name of the language. The name "Karnataka" is derived from the Sanskrit term "Karna" (ear) and "Desha" (land), referring to the region's historical and cultural heritage, but it does not directly incorporate the name of the official language.
Kerala: The official language of Kerala is Malayalam. The state name "Kerala" does not include the name of the language. The name "Kerala" is derived from the ancient Tamil word "Keralam," which has historical and cultural significance, but it does not directly incorporate the name of the official language.
Thus, the only state among the options where the name of the state includes the name of its official language is Tamil Nadu. This unique characteristic makes Tamil Nadu stand out in the context of Indian states and their official languages.
