Answer- B. Amygdala
The white fibers marked in the given figure are anterior commissure fibers. The fibers of the anterior commissure can be traced laterally and posteriorly on either side beneath the corpus striatum into the substance of the temporal lobe. It serves in this way to connect the two temporal lobes, but it also contains decussating fibers from the olfactory tracts and is a part of the neospinothalamic tract for pain. The anterior commissure also serves to connect the amygdala.
