Correct answer
D X-longer, Y - shorter

Step-by-step explanation

According to bent rule more electronegative atom occupy less s-character so bond length increases. O-H bond will be short than O-F bond due to small size of H than F. Correspondingly, O-O bond in hydrogen peroxide will be shorter than that of O2F2. Corresponding structures are:
