Step 1: Understanding the Question.
The question is asking about the language-family relationships. The terms refer to the linguistic classification of the languages based on their ethnolinguistic group.
Step 2: Evaluating the Options.
- (1) Dravidian - Ho: This is the correct answer, as the Ho language belongs to the Dravidian language family.
- (2) Austro-Asiatic - Khasi: Khasi belongs to the Austro-Asiatic language family, but the pairing does not match with the correct language family here.
- (3) Nepali - Indo-Aryan: This is incorrect because Nepali is part of the Indo-Aryan family, but it is not associated with the Ho language.
- (4) Tai-Ahom - Tai: This is incorrect, as Tai-Ahom belongs to a different group entirely and does not match with Dravidian - Ho.
Step 3: Conclusion.
The correct answer is (1) Dravidian - Ho, as it correctly represents the Dravidian language family with the Ho language.
