Q.Which of the following Gymnosperm plant produces amber ?

Amber is fossilised resin, and the classic source gymnosperm cited in textbooks is the fossil conifer Pinites succinifera.

Gymnosperms, especially conifers, characteristically secrete resin - a viscous, protective substance - from resin ducts in their wood and bark. Over millions of years, resin that has hardened, fossilised, and undergone chemical change can form amber, a golden, translucent, gemstone-like fossil material (well known from Baltic amber deposits, sometimes containing trapped ancient insects). The extinct conifer Pinites succinifera is the fossil gymnosperm classically credited as the main source of this fossil resin/amber.
