Step 1: Understanding the word "pragmati(C)"
"Pragmatic" refers to dealing with things sensibly and realistically, based on practical considerations rather than theoretical ones.
Step 2: Analyzing the options.
- Practical means dealing with things in a realistic and sensible way, similar to "pragmati(C)"
- Sensible refers to being practical or reasonable, also similar to "pragmati(C)"
- Proficient refers to being skilled or competent, which is unrelated to pragmati(C)
- Utopian refers to an idealistic or perfect vision, which is the opposite of pragmatic because it lacks a practical, realistic basis.
Step 3: Conclusion.
"Utopian" is the opposite of pragmatic because it refers to an unrealistic or idealized vision, while "pragmatic" deals with practical and realistic approaches.
Thus, the correct answer is 4. Utopian.
Final Answer:
\[
\boxed{\text{The correct answer is 4. Utopian.}}
