We need to identify the incorrect pair of stain and its type. The correct classification of stains is based on their origin: animal, plant, mineral, or dye.
Step 1: Analyze the options.
- (A) Animal - Oil: This is a correct pairing as oils from animals are classified as animal stains.
- (B) Plant - Curry: This is a correct pairing as curry is derived from plants, and plant-based stains are common.
- (C) Mineral - Rust: This is also correct as rust is a mineral-based stain.
- (D) Dye - Paint: This is incorrect because paint is not classified as a dye stain. Paint is a man-made product, and dyes are natural or synthetic substances used to color materials.
Step 2: Conclusion.
The incorrect pair is (D) Dye - Paint, as paint is not a type of dye stain.
Final Answer:
\[
\boxed{(D) \, \text{Dye - Paint}}
\]
