A word arrangement machine, when given an input line of words, rearranges them following a particular rule in each step. The following is an illustration of input and the steps of rearrangement.

Input : Go for to Though By easy To Access at
Step I : Access Go for to Though By easy To at
Step II : Access at Go for to Though By easy To
Step III : Access at By Go for to Though easy To
Step IV : Access at By easy Go for to Though To
Step V : Access at By easy for Go to Though To
Step VI : Access at By easy for Go Though to To
Step VII : Access at By easy for Go Though To to
And Step VII is the last step for this input. 
As per the rules followed in the above steps, find out in the given questions the appropriate step for the given input.

Input: "every and peer to an for" Which of the following steps would be 'an and every for peer to'?

​​

Logic: Operations applied in each step are defined below:
Step I to step VII: Words are arranged in dictionary order from left to right. If there are two similar words in statement then the words with first letter in capital will be arranged first before the second one.

Input: every and peer to an for

Step I: an every and peer to for
Step II: an and every peer to for
Step III: an and every for to peer
Step IV: an and every for peer to

So, Step IV corresponds to the required arrangement.

Thus, the correct answer is (b).
