Functional Communicative Approach in English Language
Teaching is in opposition to the:

The correct option is Grammar Translation Method.

Here is a step-by-step explanation of why this option is correct:
The Functional Communicative Approach focuses on developing "communicative competence"—the ability to use language effectively and contextually in real-life situations. Its primary goal is interaction, meaning, and authentic communication, rather than the mechanical memorization of grammatical rules.

In direct opposition to this, the Grammar Translation Method is a traditional teaching methodology that emphasizes the learning of grammatical rules, vocabulary memorization, and the translation of literary texts from the target language into the native language. Under this method, there is little to no focus on oral communication, speaking skills, or active language usage in real-world contexts.

Therefore, because the Grammar Translation Method prioritizes rote memorization of structural rules and translation over functional, communicative competence, the Functional Communicative Approach stands in direct opposition to it.
