In the following question, from the given alternative words, select the word which cannot be formed using the letters of the given word.
Nightwalker
Answer: C
Correct answer: Waller
“Nightwalker” contains only one L, and “Waller” needs two, so it cannot be formed. The other three all can: talker, tailer and winer each draw a letter at most as many times as it appears. Counting the repeated letters of the source word first - here just one each of everything - is the quickest way through this type.
