Which two of your senses are linked together (i. e., influence your perception of both)?
taste and touch
touch and smell
smell and taste
taste and sight

The correct answer is smell and taste.

The sense of taste and smell are related to one another because they have the same types of receptors. Odor comes from the molecules that is present in the air that stimulates the receptors that is present inside the nose.

This is caused due to the relationship between the smell and taste receptors.
