Explanation:

- Let's analyze the relationship:

- IVORY : ZWSPJ

- Check letter-wise:

- I ? Z

- V ? W

- O ? S

- R ? P

- Y ? J

- If we look closely, each letter in the first pair is being substituted consistently by another using a certain pattern. Use the corresponding place in the alphabet (A=1).

- I (9) ? Z (26) ? 27 - 9 = 18

- V (22) ? W (23) ? 22 + 1

- O (15) ? S (19) ? 15 + 4

- R (18) ? P (16) ? 18 - 2

- Y (25) ? J (10) ? 25 - 15

- Pattern alternates, but mainly mixes shifting forward and backward with a pattern for each letter position.

- Now, let's apply the same pattern to CREAM:

- C (3) ? D?

- R (18) ? S?

- E (5) ? F?

- A (1) ? C?

- M (13) ? N?

- This leads to DSFCN.

- Option 1: DSFCN

- Option 2: NFDQB

- Option 3: BQDZL

- Option 4: SNFDB

- So, the correct option is Option 1: DSFCN
