पर्याय

• T is called sixth  

• V is called fourth  

• W is called first  

• x is called first  

Answer 1

x is called first  

Explanation:

Option 'x is called first ' is correct as W, X, and Y have to be called before V, and T has to be called at 4th position so V can come only at 5th or 6th position which leads to given possibilities 1. X, 2. W/Y, 3. Y/W, 4. T, 5. V, 6. Z or 1. X/Z, 2. Z/X, 3.Y/W, 4. T, 5. W/Y, 6. V. Thus X is called first is correct.

Option 'T is called sixth' is incorrect as T is to be called in the 4th position only.

Option 'V is called fourth' is incorrect as the only T can be called in the 4th position.

Option 'W is called first' is incorrect as X must be called before W, so W can't be called first.
