Correct answer: B
Concept
In a fixed substitution code, each letter keeps the same numeric block wherever it appears. To encode a new word, first recover each letter-to-block mapping from the examples, then concatenate the blocks in the new word’s order.
Application
Read the required mappings directly from CODE and STEP:
From STEP, S maps to 18.
From STEP, P maps to 22.
From CODE, O maps to 16.
From STEP, T maps to 76.
The repeated letter E maps to 91 in both CODE and STEP.
Cross-check
Putting the recovered blocks in the order S–P–O–T–E gives 18 | 22 | 16 | 76 | 91. The E block agrees in both examples, confirming that the substitution is consistent.
Therefore, SPOTE is coded as 1822167691.
