Which category does ESL speakers belong to?

The option indicating that ESL speakers belong to speakers of New Englishes in the 'outer circle' where English is an official language is accurate because it acknowledges the context in which English is used as a second language. In many countries classified within the 'outer circle' (a concept introduced by linguist Braj Kachru), English serves a significant role alongside local languages. This means that these speakers have an established understanding of English but it is not their first language; instead, they learn and use English for various purposes—educational, governmental, and social—within their multilingual environments. This categorization highlights the unique linguistic and cultural dynamics that shape how English evolves in these contexts, often resulting in distinct varieties known as New Englishes that reflect the influences of local languages and culture.
