“P © Q” means “P is either greater than or equal to Q”.

“P $ Q” means “P is greater than Q”.

B) If only Conclusion II is true.
C) If either Conclusion I or Conclusion II is true.
D) If neither Conclusion I nor Conclusion II is true.
E) If both the Conclusion I and II are true.
Solution:

B # D means B < D............ (i)

E @T means E≤ T............ (ii)

T © P means T ≥ P............ (iii)

P $ B means P > B............ (iv)

From (i) and (iv)

But the exhaustive possibilities are P > D, P = D and P < D.

Hence, either I or II is correct.
