In which of the following expressions does the expression ‘L > B’ and ‘R < N’ is true?

(a) Q = R > S ≥ L < T > N ≤ O > B                   No relationship can be established between L and B, R and N. Hence option 1 is not correct. (b) B > T = F < R ≥ C < N = L ≤ E                    No relationship can be established between L and B, R and N. Hence option 2 is not correct. (c) B < P > R < I > N ≥ ≥ C ≤ L                     No relationship can be established between L and B, R and N. Hence option 3 is not correct. (d) N ≥ U > K ≥ B = R ≤ W = M < L                               ‘L > B’ and ‘R < N’ is true. Hence option 4 is correct.
