Correct Answer - Option 4 : = , <, ≤ , >
Let us check each option:
1) T = O ≤ D > A > Y → False (as O ≤ D > A → no clear relation between O and A cannot be determined because there are opposite signs between O and A . So, it is false)
2) T< O > D ≤ A < Y → False (as O > D ≤ A → no clear relation between O and A cannot be determined because there are opposite signs between O and A . So, it is false)
3) T > O > D = A < Y → False ( as O > D = A → O > A . So, it is false )
4) T = O < D ≤ A > Y → True (as O < D ≤ A → O < A)
5) T< O > D ≥ A ≥ Y → False ( as O > D ≥ A → O > A . So, it is false)
Hence, the correct sequence of symbols to satisfy the given statement is =, <, ≤ , >.
