  • Statement (I) alone is sufficient to answer the question, but (II) alone is not sufficient.
  • Statement (II) alone is sufficient to answer the question, but (I) alone is not sufficient.
  • Both the statements (I) and (II) are sufficient to answer the question, but neither statement alone is sufficient.
  • Both the statements (I) and (II) together are not sufficient to answer the question and additional data are required.

The Correct Option is D

Solution and Explanation

Concept: In coding-decoding, to identify the code of a word, we compare common words in multiple statements and find their common codes.

Step 1:
Checking Statement (I).
Given: \[ \text{ROSES ARE BEAUTIFUL} \rightarrow Za\;Yb\;Xc \] Words: \[ \text{ROSES, ARE, BEAUTIFUL} \] Codes: \[ Za,\;Yb,\;Xc \] But we do not know which code corresponds to BEAUTIFUL. Thus, Statement (I) alone is not sufficient.

Step 2:
Checking Statement (II).
Given: \[ \text{GIRLS ARE BEAUTIFUL} \rightarrow Xc\;Za\;Wd \] Words: \[ \text{GIRLS, ARE, BEAUTIFUL} \] Codes: \[ Xc,\;Za,\;Wd \] Again, BEAUTIFUL cannot be uniquely identified. Thus, Statement (II) alone is not sufficient.

Step 3:
Checking both statements together.
Common words in both statements: \[ ARE,\; BEAUTIFUL \] Common codes in both statements: \[ Za,\; Xc \] But since there are two common words and two common codes, we cannot uniquely assign which code belongs to BEAUTIFUL. Hence, additional data are required.
