उत्तर
\[\ce{^144_55Cs}\]
Explanation:
Mass number:
235 + 1 = AX + 90 + 2
AX = 144
Atomic number:
92 = ZX + 37
ZX = 55
Atomic number 55 = Caesium (Cs).
Therefore, X = \[\ce{^144_55Cs}\]

Notes
There is a printing error in the options. The correct answer is \[\ce{^144_55Cs}\] (Cesium-144). If Option 1 is intended to represent this, the element symbol should be Cs instead of Ba.
