Demonstrated by variation in pronunciation (accent), word choice (lexicon), or morphology/syntax (grammar). Speakers do not make drastic enough changes to word order to sounds to where native speakers can't understand them.

• A. Variation
• B. Interference
• C. Code-switching
• D. Generalization

Answer: (A)

This item is about linguistic variation among speakers. Variation shows up as differences in pronunciation (accent), word choice (lexicon), and grammar (morphology/syntax) within a language, yet the overall message remains understandable to native speakers. The scenario describes exactly that: noticeable but not disruptive differences that still allow communication. It’s not about influence from another language causing errors (interference) or about switching between languages or dialects in a way that changes structure mid-conversation (code-switching). It’s simply normal variation in how people speak.
