What type of behavior is characterized by the display of body parts or release of a scent for the purpose of attracting a mate?

Courtship or Mating Rituals are characterized by a display of body parts in many animals, such as vultures who hold their wings apart while perched on top of trees. Release of a scent meant to attract a potential mate is also characteristic of courtship and mating rituals. in most organisms this scent is caused by pheromones released into the organisms blood and sweat. 

The story told by the student arrested for drunk driving -in the opinion of the judge who understands biology- is not plausible, humans do not produce alcohol in a fermentation pathway.

Explanation:

Options for this question are:

Plausible as long as he was not exposed to CO too long, which would have resulted in suffocation. Plausibles if his blood glucose levels were also very low. Not plausible, humans do not produce alcohol in a fermentation pathway. Not plausible, because only CO₂ build up would have that effect.

In humans, cellular respiration involves the use of oxygen to produce energy, through the oxidative phosphorylation that occurs in the mitochondria.

Under conditions where cells obtain little oxygen -as in athletes exposed to rigorous and prolonged exercise - an anaerobic pathway is activated to produce ATP, which is faster but less efficient than the aerobic pathway, where lactic acid is produced.

Alcoholic fermentation is restricted to a few anaerobic organisms - such as yeasts - capable of producing ethanol from a sugar, such as glucose or sucrose.

What makes the student's story implausible, by claiming that his body produced alcohol by staying within a carbon monoxide-laden environment, is the fact that humans do not produce alcohol when exposed to low oxygen environments, but rather lactic acid.
