Answer: Choice (C) is correct.

In the first half of the analogy, consider the degrees to which these terms refer. An ample amount means sufficient, but a copious amount means bountiful and plentiful. In choice (A), frugal and thrift are synonyms, and mean that a person is economical. There is not a significant difference in degree between these words. This is also the case for choices (B) and (D). In choice (B), lethargic and sluggish are synonyms, with no difference in degree. In choice (D), profound and insightful are synonyms that do not differ in degree. In choice (C), a significant difference exists between bad and egregious. A mistake, for example, might be bad, but an egregious mistake is extraordinarily awful, perhaps unforgivable.
