The recursive definition for the amount of the blood pressure medicine in hareem bloodstream after n hours would be 
Hence, option B is correct.
<h3>What is the recursive rule?</h3>
A rule is defined such that its definition includes itself.
Example:
F(x) = F(x-1) + c
is one such recursive rule.
Hareem takes medicine to control his blood pressure.
he takes a 25 mg pill in the morning.
Suppose that 60% of the medicine is processed by hareem's body by the time he takes a second 25 mg pill in the evening.
So, the recursive definition for the amount of the blood pressure medicine in hareem bloodstream after n hours would be;

Hence, option B is correct.
