The correct option is B None of these
The pattern is as under:
In the first step, the words are arranged in the order - 5th, 1st, 6th, 2nd, 7th, 3rd, 8th, 4th.
In the second step, the words in the previous code are arranged in the order - 4th, 5th, 3rd, 6th, 2nd, 7th, 1st, 8th. These two steps are repeated alternately for generating pass codes for the subsequent batches.
We now form the rearrangement draft as shown below:
Input: A B C D E F G H
Pass codes:
Batch I (10 am to 11 am): E A F B G C H D
Batch II (11 am to 12 noon): B G F C A H E D
Batch III (12 noon to 1 pm): A B H G E F D C
Batch IV (1 pm to 2 pm): G E H F B D A C
Rest hour (2 pm to 3 pm):
Batch V (3 pm to 4 pm): B G D E A H C F
Batch IV: there is no permanent solution for mental problems
G E H F B D A C
Input: A B C D E F G H
mental solution problems for is permanent there no
Hence, option (D) is the correct answer.
