Answer:
A). Syntactics.
Step-by-step explanation:
Synatactics is exemplified as the study associated to the set of rules that govern the structure of a particular language(also known as syntax) and the manner in which words are arranged or combined together in order to provide significant and meaningful phrases or sentences. Thus, option A becomes the correct answer as the other options correspond to the different branches of study. For Example; 'semantics'(option B) is associated with the 'study of meaning of the words' while 'pragmatics'(option C) relates to 'use of language in a social background/context'. 'Phonetics'(option D) is associated with the 'study of physical sounds(phones) of human speech' and 'Ethnocentric'(option E) implies 'perceiving the world through one's own cultural (ethnic/traditional) perspective. Therefore, option A becomes the most correct and appropriate answer to the given question.
