(B) In $Selaginella$,the megasporangium is the structure that produces megaspores.In $Pinus$ (a gymnosperm),the ovule consists of the integument and the nucellus.The nucellus is the central part of the ovule and is equivalent to the megasporangium because it is the tissue within which the megaspore mother cell undergoes meiosis to produce megaspores.Therefore,the megasporangium of $Selaginella$ is equivalent to the nucellus of $Pinus$.

The megasporangium of $Selaginella$ is equivalent to which structure of $Pinus$?
