The answer would be A.
Hope this helps you.
It is true that it is possible for a population to not evolve for a while.
There is something called the Hardy-Weinberg theorem, which characterizes the distributions of genotype frequencies in populations that are not evolving.
There are 5 Hardy-Weinberg assumptions:
- no mutation
- random mating
- no gene flow
- infinite population size
- and no selection (natural nor forced).
You can see that some of these are kinda extreme and really hard to get, but with approximations, we can work.
For example, instead of an "infinite population size" we have enough with a really large population, such that genetic drift is negligible.
Concluding, yes, it is possible (but really difficult) for a population to not evolve for a while (at least, in nature), as long as the 5 assumptions above are met.

Patients will use medications to re-establish traditional brain functions and reduce cravings. Medicines are accessible to the patients for treatment of opioid, tobacco, and white plague.
One of the drugs that have emerged in the last few years to help reduce cravings in opioid addicts is
Methadone.
There are some other drugs available to treat such addicts. For example, buprenorphine, and naltrexone are also used to treat opioid addiction.
<span>Methadone and buprenorphine controls the withdrawal symptoms and provides relief to patients facing cravings. </span>
