Resins,

-a sticky flammable organic substance, insoluble in water, exuded by some trees and other plants (notably fir and pine).

-a solid or liquid synthetic organic polymer used as the basis of plastics, adhesives, varnishes, or other products.

So, E is correct.

Option E is correct. Resins are insoluble in water and soluble in other solvents like alcohol and also as the oil or solvent evaporates, resin remains.
