Dear
Student,

15 volume H2O2 define 1ml of
H2O2 will 15ml O2 at STP So,
decomposition of 500ml, 15volume H202 will
give 500*15 = 7500ml O2
22400 ml gas means 1 mol of gas
For oxygen also 22400 ml = 1 mol oxygen = 32 gram oxygen
So,
7500 ml oxygen = 3222400×7500 gram oxygen = 10 7 gram
oxygen
So option 4 is the correct answer

Thanks and regards
