Step 1: Understanding the Concept:
This question asks for the antonym of the word PEDESTRIAN. In this context, pedestrian does not refer to a person walking. As an adjective, it means lacking inspiration or excitement; dull, ordinary, and commonplace.
Step 2: Detailed Explanation:
We are looking for a word that means the opposite of dull, ordinary, or commonplace. The opposite would be something exciting, unusual, or extraordinary.
Let's analyze the options:
\begin{itemize}
\item (A) widely known: This is closer to being a synonym for commonplace, not an antonym.
\item (B) strongly motivated: This describes a personal trait and is unrelated to the quality of being dull or common.
\item (C) discernible: This means able to be perceived or recognized, which is unrelated.
\item (D) uncommon: This means not often found or occurring; unusual. It is a direct opposite of commonplace or pedestrian.
\item (E) productive: This means producing a significant amount of something, which is unrelated.
\end{itemize}
Step 3: Final Answer:
The best antonym for PEDESTRIAN is UNCOMMON.
