  1. Statements:
    F @ N, N © D, D @ R
    Conclusions:
    I. D # F II. R S N III. R S F
    1. None is true
    2. Only I is true
    3. Only II is true
    4. Only III is true
    5. Only II and III are true
Correct Option: C

F ≥ N ...(i) N < D ...(ii) D ≤ R ...(iii)
From (i) and (ii) F and can't be compared.
Hence I does not follow.
From (ii) and (iii) N < D ≤ R or R > N ...(iv)
Hence II follows. From (i) and (iv) R and F can't be compared. Hence III does not follow.
