1. If X is the same color as Z, then it must be true that-

  • A. R is the same color as Y
  • B. R is the same color as Y
  • C. R is the same color as Y
  • D. R is the same color as Y

Answer: Option B

Explanation:

R,S, X and Y each are adjacent to W, so W can not be the same color as X, as x is the same color as Z, So W can not be the same color as Z too. So W is different from any other country.
