Solution

The correct option is D electric
All the information in the brain is processed in the form of electric signals. So whatever input we get, whether it is smell or sound, is converted to electrical signals so that the brain can read them and give out a proper response. The olfactory epithelium is present in the nose. It coverts the smell into an electrical signal which is identified by our brain, giving us a sense of smell.
