why is synthetic resin preferable to natural resin?

a. Synthetic resin will not yellow, crack, or dissolve in liquid.
b. Synthetic resin will not yellow, obscure, or damage the painting.
c. Synthetic resin will not destroy paint pigment, crack, or yellow the painting.
d. Synthetic resin will not damage the canvas, dissolve in liquid, or muddy the painting.

The correct answer is c. Synthetic resin will not destroy paint pigment, crack, or yellow the painting.

Synthetic resins are often preferred over natural resins because they have a higher resistance to chemical degradation, are less likely to yellow over time, and do not cause damage to the artwork. Natural resins, on the other hand, have a higher likelihood of cracking, yellowing, or dissolving in liquids, which can potentially damage the painting or alter its appearance.
