Underwater living faces many of the same life support challenges as living in space. ... But in the future, underwater habitats might provide their own oxygen with artificial gill technology to extract dissolved air from the sea water
Since humans do not have gills, we cannot extract oxygen from water. Some marine mammals, like whales and dolphins, do live in water, but they don't breathe it. They have developed a mechanism to hold their breath for long periods of time underwater.
To put these depths into perspective, three American football fields laid end to end would measure 900 feet (274.32 m) long — less than the distance these divers reached underwater. Most recreational scuba divers only dive as deep as 130 feet (40 meters), according to the Professional Association of Diving Instructors.

Answer:
B) Functional magnetic resonance imaging
Explanation:
fMRI or Functional magnetic resonance imaging is the technique which is used to measure the neural activity in the brain of humans and other animals.
The technique is based on the concept that the activity in the neurons is coupled to the flow of the blood in the neurons. The change in the rate of blood flow to the region of neurons shows that that part of the neuron is activated at that time.
Therefore by measuring the changes in the blood flow, the technique scans the neural activities of the brain.
Thus, Optio-B is the correct answer.
