    N < O ≥ R > T; R < A; B ≤ T
    Check for I:
    N < O ≥ R > T
    ∴ No definite relation can be found between N and A.
    Check for II:

    Correct Option: B

    N < O ≥ R > T; R < A; B ≤ T
    Check for I:
    N < O ≥ R > T
    ∴ No definite relation can be found between N and A.
    Check for II:

    R < F ...(i) F ≥ D ...(ii) D ≤ M ...(iii)
    From (i) and (ii) R and D can't be compared. Hence neight I nor III follows.
    From (ii) and (iii) M and F can't be compared. Hence II does not follows.

    Correct Option: A

    R < F ...(i) F ≥ D ...(ii) D ≤ M ...(iii)
    From (i) and (ii) R and D can't be compared. Hence neight I nor III follows.
    From (ii) and (iii) M and F can't be compared. Hence II does not follows.

    1. Only either I or II is true
    2. Only either I or III is true
    3. Only either I or II and III are true
    4. Only III is true
    5. None of these

    M ≥ W ...(i) W = N ...(ii) N > B ...(iii)
    Combining these we get M ≥ W = N > B.
    Hence M ≥ N or N ≤ M,
    Which means either I (N = M) or II (N < M) follows.
    Also M > B and II (M ≤ D) Hence III definitely true.

    Correct Option: C

    M ≥ W ...(i) W = N ...(ii) N > B ...(iii)
    Combining these we get M ≥ W = N > B.
    Hence M ≥ N or N ≤ M,
    Which means either I (N = M) or II (N < M) follows.
    Also M > B and II (M ≤ D) Hence III definitely true.

    M ≥ W ...(i) W = N ...(ii) N > B ...(iii)
    Combining these we get M ≥ W = N > B.
    Hence M ≥ N or N ≤ M,
    Which means either I (N = M) or II (N < M) follows.
    Also M > B and II (M ≤ D) Hence III deficitely true.
