Efforts to document and preserve smaller languages in Meghalaya might involve:

The correct answer is: d) All of the above

Efforts to document and preserve smaller languages in Meghalaya might involve:

• Creating dictionaries and grammars. This is essential for documenting the structure and vocabulary of a language, and for making it accessible to speakers of other languages.
• Developing writing systems. If a language does not have a writing system, one needs to be developed in order to record it. This can be a complex process, as it involves creating a system of symbols that can represent the sounds of the language.
• Oral history projects. These involve collecting stories and other information about a language and its speakers from older people who remember it well. This information can be used to document the history of the language, as well as its cultural and social context.

All of these efforts are important for preserving smaller languages, as they help to ensure that they are not lost or forgotten.
