Explanation:

Certainly! Let's analyze the pattern:

- SHELVES: Each letter is given a value according to its position in the alphabet (S=19, H=8, E=5, L=12, V=22, E=5, S=19). The sum is 90. However, it is coded as 100. Therefore, the code involves adding 10 to the sum.

- TURNING: The sum of the positions is calculated (T=20, U=21, R=18, N=14, I=9, N=14, G=7), resulting in 103. When coded as 87, 16 is subtracted from the sum.

Using the same logic for REDRESS:

- R=18, E=5, D=4, R=18, E=5, S=19, S=19. Sum = 88

- It seems we're using direct sum without adjustments as in TURNING.

- Option 1: 89

- Option 2: 88

- Option 3: 102

- Option 4: 101

The sum is 88, not adjusted like in SHELVES or TURNING.

88 is the correct code for REDRESS.
