ExplanationThe girl could always find something else that displeased her which means that she must be a habitual complainer. She may be an impertinent complainer, but there is no evidence that she was rude in the way she complained.
The same problem exists with choices (C) and (F). Oblique, which means not straightforward, does not make sense in context, which rules out choice (D).
Inveterate and chronic are synonyms for habitual,
so choices (A) and (E) are correct.
