The establishment of English as a global lingua franca...

A As a lingua franca, English adapts to various sociocultural contexts, often displaying grammatical simplifications and lexical influences from local languages. B English, as a lingua franca, exclusively preserves the grammatical and phonological norms of British English, ensuring global standardization.  C The use of English as a lingua franca is an exclusively post-colonial phenomenon, limited to the 20th century and restricted to former British colonies. D The function of English as a lingua franca prevents the emergence of new local varieties, such as Englishbased pidgins or creoles.  E English as a lingua franca is used exclusively in formal settings, such as international business and academic conferences, without impacting everyday interactions.
