The given reaction is: 
11eaa8f0_66f6_d091_93a6_2fe46d903e43_TB6423_11 → 11eaa8f0_66f6_f7a3_93a6_2f2dcf5f07a0_TB6423_11 + O
As per the law of conservation of mass, the rate of disappearance of Ozone must be equal to the rate of appearance of oxygen. 
Hence, the rate of appearance of 11eaa8f0_66f6_f7a3_93a6_2f2dcf5f07a0_TB6423_11 would also be 11eaa8f0_66f6_d092_93a6_6dfb6332bcba_TB6423_11 atm. 
Therefore, the answer is A.

The Average Rate of Disappearance of Ozone in the Reaction
