Coding — How is 'never' written in the code language? Statements: I. 'never ever go there' → 'na ja ni ho'. II. 'go there and come back' → 'ma ho sa ni da'.

Introduction / Context:We must identify the unique code token for the English word 'never' via overlapping coded sentences.

Given Data / Assumptions:

• S1: 'never ever go there' ↔ {na, ja, ni, ho}.
• S2: 'go there and come back' ↔ {ma, ho, sa, ni, da}.
• One-to-one mapping per sentence; tokens are word-level.

Concept / Approach:Intersect common words and codes to eliminate shared pairs; leftover tokens in S1 would correspond to {never, ever} but remain ambiguous.

Step-by-Step Solution:

Verification / Alternative check:No arrangement of the S2 tokens resolves the tie between {na, ja}.

Why Other Options Are Wrong:

• A/B/C/E: Neither statement alone nor both together can uniquely assign 'never'.

Common Pitfalls:Assuming alphabetical/semantic hints; DS forbids using such external cues.

Final Answer:D — Together not sufficient.
