Answer: D. Hypothesis B is more useful because it suggests a way to test the relationship between heart rate and caffeine intake.

Hypothesis A and B both are suggesting that caffeine intake is related to higher heart rate. But hypothesis B is proving it more certainly by suggesting the affects of caffeine intake on heart rate.

Answer: The correct option is D (Antimicrobials).

Explanation:

Antimicrobial treatment is defined as therapies that are given to patients to either inhibit or kill the growth of microorganisms IN their body cells. The antimicrobial treatment can be grouped into two based on their mechanism of action. These includes:

--> Microbiocidal therapy: This type of treatment when given, kills the microorganisms in the cells of the patient.

--> Microbiostatic therapy: This type of treatment aims at inhibiting the growth of microorganisms when administered to a patient.

The antimicrobial drugs achieve their role usually through their different modes of action which includes:

--> cell wall inhibition

--> inhibition of cell membrane function

--> protein and nucleic acid synthesis inhibition.

Disinfects, antiseptic and sterilisation are all different ways of eliminating microorganisms but not used as invitro (within) treatment for patients. Therefore the term that best matches the description given is antimicrobials.
