Read the following statements.
Statement (A): Chemical senses of olfactory and gustatory are functionally similar and interrelated.
Statement (B): Neurons of olfactory epithelia extend from outside environment directly into olfactory bulbs which are extensions of brain's limbic system.

The neurons of the olfactory epithelium extend from the outside environment directly into a pair of broad bean-sized organs, called olfactory bulb, which are extensions of the brain’s limbic system. The chemical senses of gustation (taste) and olfactory (smell) are functionally similar and interrelated.
