In the option C, touch is the stimulus. The contraction of the protozoa is the response.
In the option D, the smell of food is the stimulus. Rumbling of the stomach is the response.

Answer:
The correct answer is B: Cohesion
Explanation: 
<u>Cohesion</u> is the ability of water molecules to be strongly bonded together. This happens due to the polarity of water molecules. Since water is made up of two positive hydrogen ions that combine with one negative oxygen ion to form a hydrogen bond. Hence, the molecular structure of water enables hydrogen irons to attract oxygen ions that create a strong polar bond between water molecules.
