Final answer:
When contaminants stick to resin or GAC, the process is called absorption. The substance has yielded the most antimicrobial activity-related compounds is soil, due to its rich microbial diversity and the production of inhibitory substances.option B) Absorb
Step-by-step explanation:
When contaminants stick to resin or GAC (Granulated Activated Carbon), it is said to absorb. Absorption is a process where a substance takes up another substance through molecular or chemical means. It is important to understand that absorption is different from adsorption, where a substance adheres to the surface of another without being taken into the internal structure.
In the context of antimicrobial activity, the option that has yielded compounds with the most antimicrobial activity is D. soil. Soil is a rich source of various microorganisms, some of which produce substances to inhibit or kill competing microbes. These substances can be extracted and have antimicrobial properties, making soil a significant source for discovering new antibiotics and antimicrobial compounds.
