Step 1: Understanding the Question:
We are asked to identify the antonym for the word "CHIMERICAL".
We will define its literary meaning and evaluate the options.
Step 2: Detailed Explanation:
The word "CHIMERICAL" is an adjective derived from the "Chimera", a mythical Greek beast composed of parts from different animals (a lion, goat, and serpent).
In modern usage, it describes something that is wildly fanciful, highly improbable, or existing only as a product of an unchecked imagination.
It refers to hopes, plans, or illusions that are impossible to achieve in reality.
For example, "His dream of establishing a utopian colony on Jupiter was entirely chimerical."
Let us evaluate Option (A) "exact".
Exact means accurate or precise in every detail. It does not directly contrast with the concept of being imaginary.
Let us evaluate Option (B) "real".
Real means actually existing as a thing or occurring in fact; not imagined or supposed.
Since chimerical means entirely imaginary and non-existent, "real" is its perfect logical antonym.
Let us evaluate Option (C) "obvious".
Obvious means easily perceived or understood. Unrelated.
Let us evaluate Option (D) "particular".
Particular is used to single out an individual member of a specified group. Unrelated.
Let us evaluate Option (E) "talkative".
Talkative means fond of or given to talking. Completely unrelated.
Therefore, "real" is the correct antonym.
