Step 1: Understanding the concept of Extremely Backward Class (EBC).
The Extremely Backward Class (EBC) refers to castes that are considered to be more socially and economically disadvantaged than others. These castes often face social exclusion and have access to affirmative action programs to help improve their status.
Step 2: Identifying the castes that belong to EBC.
Teli, Nonia, and Nai are traditionally classified as EBC castes, as they are considered to be economically backward and socially marginalized in many regions of India.
Step 3: Identifying the outlier.
Yadav, on the other hand, is a caste that is generally considered to be socially and economically more prominent compared to other backward classes, and is not categorized under the Extremely Backward Class (EBC) category in most states.
Step 4: Conclusion.
Yadav does not come under the Extremely Backward Class (EBC).
Final Answer: \[ \boxed{\text{The correct answer is (D) Yadav.}} \]
