Correct answer: A
Key insight: each letter corresponds to a fixed number deduced from the examples.
From CASUAL we get: C → 11, A → 19, S → 14, U → 16, L → 56
From REFER we get: R → 18, E → 34, F → 72
Now encode REFUSAL (letters in order):
R → 18
E → 34
F → 72
U → 16
S → 14
A → 19
L → 56
Concatenate the codes in order: 18 34 72 16 14 19 56 → 18347216141956
Answer: 18347216141956
