Step 1: Conceptual Framework: This question assesses the ability to associate specific stain types with their corresponding chemical removal agents. Varied stains necessitate distinct chemical interventions (e.g., solvents for lipid-based stains, alkaline solutions for proteinaceous stains, oxidizing agents for dye-based stains).
Step 2: Detailed Analysis and Matching: Prioritize the most definitive pairings.
(C) Lipstick: Lipstick comprises waxes, oils (grease), and pigments. Its removal requires a solvent. (I) Methylated spirit functions effectively as a solvent for such stains, establishing C -> I as a robust match.
(A) Blood: Blood is a protein-based stain. For recalcitrant bloodstains, a mild alkali is employed to degrade the protein. (III) Ammonia, a weak alkali, is commonly recommended for this purpose following initial cold water soaking. Thus, A -> III is a strong correlation.
Given the pairings C->I and A->III, review the provided options. Only option (4) incorporates both these associations. Proceed to validate the remaining pairings within option (4).
(B) Tea/Coffee: These stains are derived from tannins. A mild alkali, such as (IV) Borax, presents a well-established and efficacious home remedy for their elimination. Therefore, B -> IV is a correct match.
(D) Curry: Curry stains are predominantly due to turmeric, a potent natural dye. Their complete removal, particularly from lighter fabrics, frequently necessitates a bleaching agent. (II) Javelle water, a solution of sodium hypochlorite, is a strong bleaching agent and represents a feasible match for addressing stubborn curry stains on appropriate materials (e.g., white cotton).
Step 3: Conclusion: All pairings presented in option (4) are accurate and conceptually sound for stain removal procedures. The correct sequence is (A) - (III), (B) - (IV), (C) - (I), (D) - (II).
