Explanation:

Cohesion is the attraction between like molecules. Since water molecules are attracted to other water molecules (like - like), this is cohesion. Adhesion is the attraction between unlike molecules. Water molecules (polar) and cotton string (which can have polar - like groups due to cellulose structure) are unlike, so this is adhesion.

Answer:

A. Cohesion
B. Adhesion
