Task: Class Definition Understanding (ontology: Sciences/Biology)

Which of the following definitions best describes 'lamina of septum pellucidum'?

A. Regional part of telencephalon in some species, e.g., rodent, equivalent to the the concept (caudate nucleus and putamen). Unlike the the concept of primates, for example, the the concept is not split into separate nuclei by the fibers of the internal capsule. Rather, the internal capsule splits into fiber bundles which course through the structure.
B. The layers of the laminar structure of the hippocampus.
C. One of two layers of both white and gray matter of the septum pellucidum. During fetal development there is a space between the two laminae called the cavum septum pellucidum which, in ninety per cent of cases, disappears during infancy.
D. Inner third of the dentate gyrus.

Answer: One of two layers of both white and gray matter of the septum pellucidum. During fetal development there is a space between the two laminae called the cavum septum pellucidum which, in ninety per cent of cases, disappears during infancy.
