Answer

Analysis of Directions Provided
To determine the best direction based on the advice from the four individuals, we need to analyze each person's recommendations.
Responses from Individuals
- A's Advice: Go to any one of west, south, north-east.
- B's Advice: Do not go west, north-east, or south-west.
- C's Advice: Not to go to east, south, and north-east.
- D's Advice: Not to go to east, north, north-east.
Summary of Directions to Avoid
- West: Advisable according to A, but advised against by B.
- South: Advisable according to A, but advised against by C.
- North-east: Advisable according to A, but advised against by B, C, and D.
- East: Not recommended by C and D.
- South-west: Not mentioned by anyone, which implies it's a potential option.
- North: Not recommended by D.
Majority Opinion
Now, let's tally the advice:
- West: 1 support (A) vs 1 against (B) = No majority.
- South: 1 support (A) vs 1 against (C) = No majority.
- North-east: 1 support (A) vs 3 against (B, C, D) = Majority against.
- East: 0 support vs 2 against (C, D) = Majority against.
- South-west: No mentions = Implied support.
- North: 0 support vs 1 against (D) = Minority against.
Conclusion
Based on the majority opinion, the options left are West or South from A’s advice. Since both options have an equal number of proponents and opponents, the decision should lean towards either west or south, making option A the correct choice.
