................ refers to “the embedding of linguistic units such as phrases, words, and morphemes of one language in an utterance of another language.”

Correct option is B

Code-switching involves the embedding of linguistic units from one language into an utterance in another language. This is common in multilingual communities and reflects speakers’ ability to adapt to different social and linguistic contexts.
Information Booster:
1. Code-switching occurs for pragmatic purposes, like emphasis or clarity.
2. It often signifies cultural identity and group affiliation.
3. In bilingual speech, it allows speakers to express ideas more fluently.
4. Sociolinguists study code-switching to understand language interaction and adaptation.
Additional Information:
· (a) Language-shifting: Refers to adopting a different language entirely, not embedding units.
· (c) Code-shifting: Incorrect term; similar to language-shifting but not linguistic embedding.
· (d) Creolism: Refers to the development of Creole languages, unrelated to code-switching.
