But how? 
Amit said: (Aug 30, 2015)  
Mass number of H = 2. Mass number of O = 32. Ratio = 16. 
Kumaresh said: (Oct 18, 2015)  
Molecular weight of H = 2.016. Molecular weight of O = 32. So 32/2.016 = 15.87 = 16. 
Anand said: (Oct 18, 2016)  
Molecular weight of O is 16 only. For O2 > 32. So, the answer is 16/2 = 8. 
Tushar Sanghi said: (Mar 17, 2017)  
The answer should be 8. 
Er Dheeraj Yashraj said: (Jul 25, 2017)  
The answer is 8. 
Rajnikant said: (Jul 26, 2017)  
Yes, answer should be 8. 
Akash said: (Oct 24, 2017)  
According to me, the correct answer is 8. 
Mohtesan Maqsood said: (Oct 25, 2017)  
Atomic mass of hydrogen is 1 & oxygen is 16. So, the oxygen atom is 16 times heavier than a hydrogen atom. 
Swithin said: (Nov 10, 2017)  
Atomic weight of hydrogen is 1 and oxy is 16. 
Deepak S said: (Feb 26, 2018)  
The molar mass of O2 = 2*16 = 32 The molar mass of H2 = 2*1 = 2 As w.k.t. atomic mass of both oxygen and hydrogen is 16 and 1 respectively, Hence ratio of their masses = 32/2 = 16. 
Surendra said: (Apr 8, 2018)  
Atomic mass of H = 1, Atomic mass of O =16. So, the ratio of the atomic mass of both is 16. Oxygen atom 16 times heavier than hydrogen atom. 
Sparta Somu said: (Apr 19, 2018)  
O+O =O2. 16+16 =32, 16/2 + 16/2 = 32/2, 8+8=16. 
Shahbaz Ali said: (Jul 4, 2018)  
Atomic mass of Oxygen is 16. Atomic mass of Hydrogen is 1. So it's ratio is 16/1=16. Answer. So, option is D
