A. Transliterations is incorrect because it’s the process of changing the form of a word or letter into another language; it has nothing to do with standard english.
C. Parts of speech is incorrect because it has to do with sentence structures and not with the standards of English. Parts of speech is the characterization of words, such as nouns, verbs, adjectives and adverbs.
D. Technical jargon is incorrect because jargon are words that are mostly used by people of a certain profession. These words do not fall under standard English because they’re not commonly used, thus, not usually understood.
