Choose the correct statements with regard to the binary pair Langue and Parole introduced by Ferdinand de Saussure:
A. Langue is translated as speech and parole as language.
B. Langue is the internal structure of a language; not language itself.
C. Parole is the event of language.
D. Parole and language are a set of vocabulary only.
E. There is no distinction between Parole and Langue.
Choose the correct answer from the options given below

The correct option is C and B only.

Let us analyze the concept of Langue and Parole introduced by the Swiss linguist Ferdinand de Saussure to understand why statements B and C are correct:

1. Understanding Langue (Statement B):
Saussure defined Langue as the abstract, systematic, and collective rules and structure of a language (like grammar, syntax, and spelling) that exists in the minds of a community of speakers. It is the underlying system that makes speech possible, rather than any individual instance of speech itself. Therefore, statement B ("Langue is the internal structure of a language; not language itself") is correct.

2. Understanding Parole (Statement C):
Saussure defined Parole as the concrete, individual instances of language use in real-life situations (actual speech or writing). It is the execution of the system of Langue by an individual speaker. Thus, it represents the specific event or act of language. Therefore, statement C ("Parole is the event of language") is correct.

3. Why the other statements are incorrect:
- Statement A: This statement is incorrect because it reverses the definitions. Langue is translated as "language" (the system), and Parole is translated as "speech" (the act).
- Statement D: Parole is not merely a set of vocabulary; it is the physical realization of the language system in speech, while language (or Langue) is the entire structural system, not just a list of words.
- Statement E: Saussure's structural linguistics is founded on the very distinction between Langue and Parole, making this statement false.

Consequently, the only correct statements are B and C, which matches the option C and B only.
