Vedclass · Answer

(C) $Araucaria$ is a genus of evergreen coniferous trees in the family $Araucariaceae$.In $Araucaria$,the scale leaves are indeed small,brown,and often dry or membranous,which is a characteristic feature of many gymnosperms.Therefore,Assertion $(A)$ is true.However,$Araucaria$ is a gymnosperm,and in gymnosperms,the sporophyte is the dominant,long-lived,and independent phase.The gametophyte phase is highly reduced,dependent on the sporophyte,and not subterranean.Therefore,Reason $(R)$ is false.Thus,the correct option is $C$.

Assertion $(A)$: The scale leaves of $Araucaria$ are small and brown.
Reason $(R)$: The gametophyte stage of $Araucaria$ is long-lived and subterranean.
Which option is correct for Assertion $(A)$ and Reason $(R)$?
