  1. A. I only
  2. B. II only
  3. C. Both I and II (Correct answer)
  4. D. Neither I nor II

Correct Answer

Option C — Both I and II

Detailed Solution & Explanation

The correct answer is Both I and II.

Key Points

  • Total matches = 3 (P vs Q, P vs R, Q vs R).
  • Points: P=3, Q=2, R=1. Total = 6 = 3 wins worth 2 pts each → all results are decisive (no draws)... but P=3 must come from 1 win + 1 draw.
  • P draws with Q (1+1), P beats R (2). P=3✓.
  • Q: drew with P (1), beat R (2)?
  • Q=3≠2. Try: P beats Q (2), P draws R (1). P=3✓.
  • Q beats R (2)=Q total 2✓.
  • R: 1 from draw with P=1✓.
  • Check Statement I: P vs Q → P wins, not a draw.
  • Statement I says P-Q is a draw with 0-0 → FALSE.
  • Statement II: Goals — each team scored exactly 1 goal total in tournament.
  • R scored 1 goal; it was against Q (since R lost to P with P scoring, R scored 0 against P, so R's 1 goal was against Q). Statement II: TRUE. Only II is correct. Answer: II only.
