Show answer & explanation
Correct answer: C
Key idea: In a four-player card game, partners sit opposite each other.
Using Statement I (D is sitting opposite A): If D is opposite A, the two remaining players must be opposite each other, so B and C are partners. Hence Statement I alone is sufficient to determine C's partner (B).
Using Statement II (B is sitting right of A and left of D): 'B right of A' means B is immediately clockwise of A, and 'B left of D' means B is immediately counterclockwise of D. Together these relations imply D is two seats clockwise from A, i.e., D is opposite A. That leaves B opposite C, so Statement II alone is also sufficient to determine C's partner (B).
Conclusion: Each statement by itself is enough to conclude that C's partner is B, so either statement alone is sufficient.
