Match the following :

Codes : (a) (b) (c) (d)

Answer: A

The correct matching is a-ii, b-i, c-iv, d-iii.

Oils in oil-based paints, such as linseed oil, are triglycerides of fatty acids (ii).
Pigments are mostly inorganic oxides, such as titanium dioxide and iron oxides (i).
Solvents are organic liquids that dissolve the binder and evaporate as the paint dries (iv).
Latex paints use binders of acrylic or vinyl polymers dispersed in water (iii).

Only the first code gives (ii), (i), (iv), (iii). The last code swaps solvent and latex.
