Answer:
Option C = Ozone
Explanation:
The Percentage of given gases in atmosphere:
Oxygen = O₂ = 20.95 %
Nitrogen = N₂ = 78.08%
Argon = Ar = 0.93%
Ozone = O₃ = 0.000004%
Nitrogen is most abundant gas in atmosphere while oxygen is second most abundant gas. The nitrogen and oxygen are present in diatomic form such as O₂ and N₂.
Water vapors are also present but the percentage vary according to location. In hot humid areas the percentage of water is 0- 4% and it is third abundant gas.
The percentage of other gases in atmosphere are given below:
CO₂ = 0.0360%
Ne = 0.0018%
He = 0.0005%
CH₄ = 0.00017 %
N₂O = 0.0003%
H₂ = 0.00005%

B/c it targets the cell replication process of white blood cells
The answer would be the second option. The best reason for doing more background research after making an observation and before forming a hypothesis is to prevent making the same mistakes made in a prior experiment. It is to make sure that you are able to see the problems of a research and make an experimental design that will minimize the errors.
