Answer

The correct option is D (Eight)

By thoroughly analyzing the given input and the various steps of re-arrangement, it is evident that in each step, one number and one word are rearranged. In the first step, the highest number and the word that appears last in alphabetical order are moved to the extreme left position. In the next step, the second highest number and the word that comes second last in alphabetical order are moved to the extreme left position. This procedure continues until all the numbers are arranged in ascending order and all the words are in alphabetical order.

Input:

store 95 clean 56 tape 15 break 28 feet 35 wait 69 ice 71

Step I:

95 wait store clean 56 tape 15 break 28 feet 35 69 ice 71

Step II:

71 tape 95 wait store clean 56 15 break 28 feet 35 69 ice

Step III:

69 store 71 tape 95 wait clean 56 15 break 28 feet 35 ice

Step IV:

56 ice 69 store 71 tape 95 wait clean 15 break 28 feet 35

Step V:

35 feet 56 ice 69 store 71 tape 95 wait clean 15 break 28

Step VI:

28 clean 35 feet 56 ice 69 store 71 tape 95 wait 15 break

Step VII:

15 break 28 clean 35 feet 56 ice 69 store 71 tape 95 wait

Step VII is the last step of the given input. In this step, there are eight elements between 'feet' and '15'.
