Scientist: In testing whether a baby's babbling is a linguistic task or just random sounds, researchers videotaped the mouths of babies as they babbled. They discovered that babbling babies open the right sides of their mouths wider than the left. Past studies have established that during nonlinguistic vocalizations people generally open the left side of the mouth wider. So babbling turns out to be a linguistic task.
Which one of the following most accurately describes how the scientist's argument proceeds?
(A) It describes an argument for a given conclusion and presents a counterargument to suggest that its conclusion is incorrect.
(B) It questions the adequacy of a generally accepted principle by providing evidence to undermine that principle, and offers a different principle in its place.
(C) It raises a question, describes a potential experimental test, and argues that the test is necessary to answer the question.
(D) It describes an explanation for some facts, counters assertions that the explanation is unlikely to be correct, and concludes that it is correct after all.
(E) It presents two possible interpretations of a phenomenon and provides evidence in support of one interpretation and against the other.

From my understanding of the argument,
Experimental setup : Researchers videotaped the mouths of babies as they babbled(in order to determine,
if the babbling was just random sounds/a linguistic task)
Interpretation 1 : Discovery that babies babbled with the sides of their mouths opened wider than the left.
Interpretation 2 : Non linguistic vocalizations people generally open the left side of the mouth wider.
Since the babies babbled with the right sides opened wider,
the scientist concludes that the babbling(the babies do) is a linguistic task.
This argument can be accurately described using the following answer option
"presenting two possible interpretations of a phenomenon and provides evidence
in support of one interpretation and against the other"(Option E)
