Correct answer: B
Concept: In a colour/word-substitution data-sufficiency question, a statement is sufficient for finding a term's new code ONLY IF that term appears as one of the ORIGINAL words being renamed somewhere in the statement's own list — appearing merely as someone else's new name does not count. Sufficiency must be judged statement-by-statement, never by combining the two.
Application: Checking each statement separately for whether it renames green (the colour asked about) directly:
Statement I renames blue, red, and orange. Green shows up only as the new name given to blue — it is never itself one of the words being renamed — so Statement I never assigns green a code and is NOT sufficient alone.
Statement II renames yellow, white, green, and brown. Here green is directly one of the original words being renamed, and it is assigned a new code outright — so Statement II alone IS sufficient.
Cross-check: Scanning Statement I again for any indirect chain that eventually reaches green confirms there isn't one, since none of blue, red, or orange is itself a renaming of green. Statement II needs no chaining at all — it states the green mapping directly — confirming the sufficiency split is exactly 'II alone, not I alone'.
So the colour of fresh grass (green) is given a new code only in Statement II, green → brown, making 'II alone is sufficient while I alone is not sufficient' the correct choice.
