-
DEither statement I or statement II alone is sufficient.

Answer
Correct Answer: Even both statements I and II together are not sufficient.
Explanation
From the two statementsCommon word = ‘‘clear’’ ⇒ common code = ‘‘de’’.Then in Statement I, {‘‘sky’’, ‘‘is’’} map to {‘‘ra’’, ‘‘fa’’} but we cannot distinguish which is which.
ConclusionEven together, the code for ‘‘sky’’ is ambiguous between two codes.
Final AnswerEven both statements I and II together are not sufficient.
