- Most
- Often
- Else
- None of these
The correct answer is “else” because it completes the common English idiom “nothing else but,” which is used to emphasize that something is purely and solely what is stated, with no other qualities or elements. In this sentence, “It is nothing else but fraud” strongly asserts that the subject is entirely fraudulent, leaving no room for alternative interpretations. The word “else” functions as an adverb meaning ‘otherwise’ or ‘in addition,’ but in this fixed phrase, it serves to intensify the exclusivity of the description. The other options are grammatically and idiomatically incorrect in this context. “Most” is a superlative adjective, “often” is an adverb of frequency, and “none of these” is a phrase used to reject given options, not to complete an idiomatic expression. Therefore, “else” is the only word that fits logically and idiomatically to convey the intended meaning of absolute certainty about the fraudulent nature of the subject.
