Mahe, which is a part of the union territory of Puducherry, is located within the state of Kerala. It is a small territory that does not directly border Karnataka. Therefore, Mahe (Puducherry) is the correct answer as it is the only option that does not share a border with Karnataka.
Understanding the geographical layout of Indian states is essential for various competitive exams, including UPSC, SSC, State PSC, and Bank PO. It is important to remember the specific borders and the states that share them to avoid common misconceptions and to accurately answer questions related to Indian geography.
