Concept:
This question focuses on descriptive adjectives related to texture and shape. Corrugated describes a specific pattern of folds or ridges. We must find the option that most closely mimics the idea of a non-smooth, folded surface.
Step 1: Understanding the structure of "CORRUGATED".
To corrugate is to shape into alternate ridges and grooves. You often see this in "corrugated iron" or "corrugated cardboard," which has a wavy middle layer to provide strength. The key characteristic is that the surface is folded or uneven.
Step 2: Eliminating opposites.
• Straightened: The act of making something flat/smooth (Opposite).
• Flattened: The act of removing ridges (Opposite).
• Pressed: Often implies making something smooth by using weight or heat (like pressing clothes).
Step 3: Choosing the synonym.
The word "wrinkled" describes a surface that has small folds or ridges. While "corrugated" is usually an intentional, industrial pattern and "wrinkled" is often accidental, they both describe a surface that is folded rather than smooth. Among the options, "wrinkled" is the nearest in meaning.
Final Answer: Option B
