Given: C < O > K; Z < R < N = C On Combining: Z < R < N = C < O > K Conclusions: 1. R < C → True (as R < N = C) 2. Z > N → False (as Z < R < N; therefore Z < N) 3. O = R → False (as R < N = C < O; therefore R < O) 4. C < K → False (as C < O > K; thus, a clear relation between C and K cannot be established) Hence, “R < C” is definitely true among the given options.
