Concept:Use the given facing directions and positions to fix the seating arrangement for each row.
Explanation:From Statement (I): R sits to the immediate left of Q, so Q cannot be at the rightmost position in Row 2.
Q faces A, hence A is exactly opposite Q in Row 1.
B sits to the immediate left of A, so B must be placed immediately beside A on A's left side.
The only possible arrangement in Row 1 is: B, A, C.
Therefore, C sits at the right extreme end of Row 1.
So, Statement (I) alone is sufficient.
From Statement (II): Only one person sits between B and C, so B and C are at the two ends of Row 1.
B faces an immediate neighbour of Q, but this does not fix B's exact end.
So, the right extreme end of Row 1 cannot be uniquely determined.
Thus, Statement (II) alone is not sufficient.
Answer:Data in Statement I alone is sufficient to answer the question while data in Statement II is not.
Hence, the correct option is B.
