Correct Answer - Option 3 : I, II and III
The Social Aspects of Language: Our choice of words, our selection of sentences are always dependent on the factors such as, the context, the person who speaks to, the place where we speak and the theme. We don’t speak to our father about our school work the same way as we speak to your mom about our food etc. Also, we cannot use the same language with our teachers the language we use with our friends. Note that:
- Social customs and norms are embedded in the language
- People's social identity is influenced by their colloquial language
- The language of a person can be understood by his social background
Hence, we conclude that all the above points are correct in the context of language.
