The correct answer here is
option E.The argument in the question is that:
Opium is sleep inducing because -> it has soporific qualities
having soporific qualities means having sleep inducing qualities, thus the argument becomes:
Opium is sleep inducing because -> it has sleep inducing qualities.
Clearly this is a case of circular reasoning where the premise or support for the conclusion is the conclusion itself.
Now the only answer choice that mirrors this is:
The company's stock price did not appreciate because -> the stock price remained stagnant (that is did not appreciate)
Hope this helps!
