c. the study of the symbols and signs that an advertisement uses
d. the study of an open or readily apparent language within an advertisement

The correct answer is B. The study of the altered meaning of words within an advertisement.

Explanation:

Semantics refers to the study of meaning in language, this implies the study of the relationship between the signifier (words, signs or symbols, including body language) and their denotation or meaning, especially as those signifiers and denotations are linked to specific communities, contexts or situations. In this way, if a study deals with the alteration of change in meaning in an advertisement it belongs to semantics as it focuses on the meaning in language or the relation between the signifier (words in the advertisement) and what it means in a specific context.
