The correct answer is A. Lingua
Explanation:
The origin and history of words is studied by a discipline known as etymology, which determines the language in which the word originated as well as the evolution of this. Due to this, in a dictionary entry including online dictionary entries, you should take a look at the section of "Etymology" to understand the origin of the word.
According to this, in the case of the entry presented to know more about the origin fo the word, the reader can read the section "etymology" and then if possible click on the link "lingua" in this section because this is the word in Latin that originated the word in English "language", and therefore by clicking in "lingua" you can get more information about the origin and evolution of the word.
