Answer:
C. Structural analysis.
Explanation:
In grammar, structural analysis refers to the process in which we make a detail examination of the different elements or structures that make up a larger part (like a word or sentence) in order to understand its essential features and nature.
So, when making a structural analysis of a word, like "subterranean", one must identify the different parts that made up the word, which are the morphemes (the most basic grammatical unit with meaning), one must determine the function of each of those morphemes (Prefix, root word or suffix) and the meaning of those parts, in order to understand the different parts of the word and the word as a whole, just as it is explained in the statement.
