Identify the antonym pair: “Introvert : Extrovert” are opposites. Choose the option that mirrors a clear opposition.

Introduction / Context:
The stem presents antonyms: introvert (inward-focused) vs extrovert (outward-focused). We must select another pair with a straightforward opposite relationship.

Given Data / Assumptions:
In everyday usage, “against” and “favour” (in favour of) represent opposing positions.

Concept / Approach:
Check each option: “Angle : Tangent” are geometric terms, not opposites; “Extreme : Interim” are unrelated; “Action : Law” is not a binary opposite; “Matter : Energy” are distinct physical concepts, not antonyms. “Against : Favour” is the clean opposite pair that mirrors the stem’s logic.

Step-by-Step Solution:

Verification / Alternative check:
Parliamentary and debate language uses “for/against” or “in favour/against” to denote opposites.

Why Other Options Are Wrong:
They are unrelated terms or not true opposites.

Common Pitfalls:
Accepting loosely related pairs that lack true polarity.

Final Answer:
Against : Favour
