Explanation:

Statements:   T = K > L ,     D > K > U  ,    C = Z < T ,     F ≥ V > U
Conclusions:  U < T,    F = K,   C < L
For conclusion I: U < T
From statements I and II, we get:
T = K > U
Here, the common sign between T and U is '>'. Thus T > U or U < T.
Hence conclusion I follows.
For conclusion II: F = K
From statements II and IV, we get:
K > U < V ≤ F
Here, we can see the opposite signs between K and F. Thus no relation can be established between them.
Hence conclusion II does not follow.
For conclusion III: C < L
From statements I, II and III, we get:
Z = C < T = K > L
Here, we can see the opposite signs between C and D. Thus no relation can be established between them.
Hence conclusion III does not follow.
Therefore only conclusion I follows.
