The question asks for the sets of Indian states that are both landlocked (meaning they do not have a coastline) and do not have an international border. Option 1 is incorrect because Andhra Pradesh has a coastline, thus it`s not landlocked. In addition, both Haryana and Andhra Pradesh have international borders. Option 3 is incorrect because both Haryana and Himachal Pradesh have international borders. Option 4 combines the issues of options 1 and 3, with Andhra Pradesh not being landlocked and both Haryana and Himachal Pradesh having international borders. Only Option 2, i.e., Chhattisgarh, Haryana, Jharkhand, Madhya Pradesh, and Telangana, contains states that are both landlocked and do not have an international border (please note that, though Haryana does not have an international boundary, it is included due to its non-coastal geographical position). Therefore, option 2 is the correct answer.
