What is amber primarily derived from?

Amber is primarily derived from a resin that oozes from ancient trees, particularly coniferous trees. Over millions of years, this resin undergoes a natural polymerization process, hardening and fossilizing into the gem-like substance known as amber. This transformation preserves not only the physical characteristics of the resin but also often encapsulates small organisms, plant matter, or air bubbles that were trapped within it during the resin's formation.

The other options describe substances that do not relate to the formation of amber. Oil extracted from coconut plants is a completely different product with distinct chemical properties and uses. A mineral found in riverbeds does not pertain to the organic origins of amber, which is a biological material, while synthetic compounds created in laboratories are entirely manufactured, lacking the natural characteristics and history associated with amber.
