In the question, a statement is followed by four conclusions. Find out which conclusion is true based on the given statement.
Statement:
Q = R > S < T < U > V = Z
Conclusions:
1. U > S
2. Q < T
3. S < V
4. Z > U

​Statement:

Q = R > S < T < U > V = Z

1. U > S; True (As S < T < U, there is a direct relation between U and S, and it concludes that U > S)​

2. Q < T; False (As Q = R > S < T, there is no direct relation between Q and T. So, no definite relation can be drawn.)

3. S < V; False (As S < T < U > V, there is no direct relation between S and V. So, no definite relation can be drawn.)

4. Z > U; ​False (As U > V = Z, there is a direct relation between U and Z, and it concludes that U > Z)

Thus, only conclusion 1 is true.

So, the correct answer is (b).
