Solution

3500 to 3000 cm-1 hydroxy stretch and 1600 cm-1 is C=C stretch clearly indicates compound X is compounds A. Compunds C, D are not possible because 3300 cm-1 sp C-H is absent. Compound B is not possible because hydroxy group is not present. Compound E is not possible because double bond is not present.
