Which pairing is correct?

Which pairing is correct?

• A. Mastic — Resin
• B. Devil's Dung — Oleogum resin
• C. Storax — Oleogum resin
• D. Balsam Copaiba — Resin

Answer: (A)

Resin is a plant exudate that becomes a hard, brittle solid, insoluble in water but soluble in organic solvents. Mastic fits this perfectly: it’s the true resin obtained from Pistacia lentiscus and is used in applications like varnishes. The other items are not pure resins. Devil’s dung refers to lac, an insect-derived secretion rather than a plant resin. Storax and copaiba balsam are mixtures that include gums and volatile oils (oleogum resins or oleoresins), not just a simple resin. So the best, most precise pairing is Mastic with Resin.
