Statement:B > R ≥ A = M < F ≤ S

Conclusions:
I B > M
II S ≥ A

Statement: B > R ≥ A = M < F ≤ S
Conclusions:
I. B > M

From the statement, A = M and B > R ≥ A.
So, B > A and since A = M, therefore B > M.
Conclusion I is true.
II. S ≥ A
Conclusion II: S ≥ A
From the given statement, the direct relation between S and A is not clearly established in definite terms.

Hence, Conclusion II does not follow.
Correct option is (a).
