When the tongue is completely removed they are able to smell the rose with the help of their nose but not able to taste (sweet and salt).

So, the correct answer is “Option C”.

Note:
The tongue detects the taste through tiny organs called taste buds, containing gustatory receptors. Humans have about more than 10,000 taste buds. The gustatory receptors bear microvilli at the free end. The microvilli have special protein receptor sites for taste producing molecules.
The gustatory receptor cells are exposed to the external surface through an opening in the taste bud called the taste pore. The gustatory receptor cells survive only about 10 days, and are replaced by new ones. There are four types of taste- sweet, sour, salty and bitter, each detected in a distinct region of a tongue.
