A question is followed by two statements numbered I and II. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and select the most appropriate answer. Six people, A, B, C, D, E and F, are sitting in a straight line, facing north. Who sits to the immediate left of E? I. B sits fourth to the right of C. Only one person sits between C and F. D sits third to the right of F. II. C sits at the extreme left end of the line. Only two people sit between C and E. A sits fourth to the left of D.
The data in both Statements I and II put together (and not independently) are sufficient to answer the question.
The data in Statement I alone is sufficient to answer the question while data in Statement II is not.
The data in Statement II alone is sufficient to answer the question while data in Statement I is not.
The data in both Statements I and II put together are NOT sufficient to answer the question.
The data in Statement I alone is sufficient to answer the question while data in Statement II is not.
Map the fixed positions in the statement to see if they create a unique arrangement for the target variable without needing extra information.

Analyze Statement I
B sits 4th to the right of C. If C is at position 1, B is at 5. One person between C and F implies F is at position 3. D sits 3rd to the right of F, which is 3+3=6. So: C(1), _, F(3), _, B(5), D(6). Remaining are A and E at 2 and 4. Since the question asks for the immediate left of E, we need to know where A and E are fixed. Actually, looking at the layout, if C=1, F=3, B=5, D=6, then positions 2 and 4 are for A and E. If E is at 2, the left is C. If E is at 4, the left is F. Wait, check placement again: B is 4th right of C means (C, _, _, _, B). Positions 1, 2, 3, 4, 5. So B is at 5. F is one away from C, so F is at 3. D is 3rd right of F (3+3=6). Sequence: 1:C, 2:?, 3:F, 4:?, 5:B, 6:D. Only A and E are left for 2 and 4. If E is at 2, left is C. If E is at 4, left is F. Statement I alone is insufficient.
Analyze Statement II
C is at 1. Two between C and E (1, 2, 3, 4: E). A is 4th left of D. If D is 5, A is 1 (taken). If D is 6, A is 2. Sequence: C(1), A(2), ?, E(4), ?, D(6). This leaves 3 and 5 for B and F. This does not fix the neighbor of E.
Combined Evaluation
Re-evaluating Statement I: C(1), _, F(3), _, B(5), D(6). With A and E to be placed. Statement II: C(1), A(2), F/B(3), E(4), F/B(5), D(6). Combining both: C(1), A(2), F(3), E(4), B(5), D(6). Immediate left of E is F.
A: Correct because both statements are required. B: Incorrect as Statement I alone is insufficient. C: Incorrect as Statement II alone is insufficient. D: Incorrect because combined data provides a unique solution.
A is correct because Statement I alone leaves E's position ambiguous, and Statement II alone leaves F and B's positions ambiguous, but combined they fix the sequence as C, A, F, E, B, D.
In seating arrangement data sufficiency, always try to draw the gaps first; if multiple scenarios exist, move to the second statement immediately to save time.
