A word arrangement machine when given an input line of words, rearranges them following a particular rule in each step. following is the illustration of the input and the steps of arrangement:
Input: she was shot dead at her residence
Step I: at was shot dead she her residence
Step II: at her shot dead she was residence
Step III: at her she dead shot was residence
Step IV: at her she was shot dead residence
Step V: at her she was dead shot residence.
Since the words are fully arranged, the machine stops. Otherwise i on till the words get fully arranged. Study the logic and answer the qu that follow:
If step II of an input reads "by he out the efforts made spells us", which of the following would be the last step ?

Options

A. Step III
B. Step IV
C. Step V
D. Step VI

Answer

C

Explanation

The logic of arrangement here is: The word with the least number of letters (at has only two letters) gets arranged first. If the number of words with the same number of letters is more than one, alphabetic preference is given. Also, arrangement is done through interchange of words. For example, since at has to occupy the first position, the position vacated by at is filled with the earlier first-position word, i.e.,she.
Step II: by he out the efforts made spells us
Step III: by he us the efforts made spells out
Step IV: by he us out efforts made spells the
Step V: by he us out the made spells efforts.
