B. `432,28. 309.47,52, 127, 116,81`
C. `432, 28, 309, 47, 127,52, 116,87`
D. `432, 28, 309, 47, 127, 116,52,37`

Answer

C

Explanation

Here, the rule followed is: The numbers are getting arranged in alternate series, one in descending order and the other in ascending order.
Step 1: The largest of the given numbers comes to the place of first number and the rest shift rightward.
Step II: The smallest of the given numbers comes to the place of second number and the rest shift rightward.
Step III: The second largest of the given numbers comes to the place of third number and the rest shift rightward.
Step IV: The second smallest of the given numbers comes to the place of fourth number and the rest shift rightward and so on until the alternate series is formed.
Input: 47, 432, 127, 52, 309, 87, 28, 116
In such case, the final step can be written direct
432,28, 309, 47, 127,52, 116,87 26
