Not all multicellular aquatic life depends on dissolved oxygen. A complex parasite that does not require oxygen to produce energy has been found in a region of the Mediterranean Sea that has virtually no dissolved oxygen due to its salinity, and three species of anaerobic loricifera have been found in the anoxic L’Atalante Basin, deriving their energy from the basin’s hydrogen-rich water by using hydrogenosomes.
The statements above, if true, best support which of the following as a conclusion?
A. The location in the Mediterranean Sea where the complex parasite was found was not one with hydrogen-rich waters that the parasite could derive energy from by using hydrogenosomes.
B. A thorough analysis of a water body’s dissolved oxygen levels is insufficient to establish beyond a doubt that the water body contains no complex life.
C. Anaerobic loricifera are able to exist in any hydrogen-rich environment.
D. Complex life probably exists on the gas giant planets, which have atmospheres that primarily consist of hydrogen and similar elements.
E. Finding the remains of complex loricifera in the bedrock would establish that the loricifera had been feeding on substances that had not been produced through the use of dissolved oxygen.

A. The location in the Mediterranean Sea where the complex parasite was found was not one with hydrogen-rich waters that the parasite could derive energy from by using hydrogenosomes.
Cannot be concluded, we don't have any evidence to conclude this. It might be possible that the location is mediterranean sea has some other organisms which depend on hydrogen-rich water so it is present there.
B. A thorough analysis of a water body’s dissolved oxygen levels is insufficient to establish beyond a doubt that the water body contains no complex life.
Can be concluded, we can only conclude about life dependent on dissolved oxygen by throughly analysing dissolved oxygen levels. Logically, it is not possible for us to determine whether the location contains other complex life just on the basis of oxygen levels because they don't depend on oxygen, we need to analyse other things like hydrogen-rich water, etc.
C. Anaerobic loricifera are able to exist in any hydrogen-rich environment.
Cannot be concluded, the argument only mentions three species of Anaerobic loricifera and that too in aquatic life. Any hydrogem-rich environment is a big jump from an aquatic life to any place.
D. Complex life probably exists on the gas giant planets, which have atmospheres that primarily consist of hydrogen and similar elements.
Cannot be concluded, we don't have any evidence to conclude this.
E. Finding the remains of complex loricifera in the bedrock would establish that the loricifera had been feeding on substances that had not been produced through the use of dissolved oxygen.
Cannot be concluded, we don't have any evidence to conclude this. We only know that it derives its energy from hydrogen-rich water.
We might make an unwarranted assumption that they also consume oxygen-free materials but it's a big gap for us to assume.

I am confident with B
Both arguments talk about the life forms. Although not origining from same place but it is crearly mentioned one was having no dissolved oxygen and other statement talking about dissolved hyderogen. Author aswell is telling about the life forms actually, One who can live without dissolve oxygen and other feeding on dissolved hydrogen. So Option B is more Ideal answer to become a conclusion.
