The answer is letter A.
Biking or bicycling is a form aerobic exercise that develops cardiorespiratory fitness. This is because the heart and lungs are the important organs that function when this activity is being done. Biking for 30 minutes to more than a few hours will inhibit the strengthening of the muscles of the heart and the ability of the lungs to convert unoxygenated blood into oxygenated blood. If you engage in this activity on a regular basis, you will notice and improvement in your performance.
From the list of individual sports in which an individual can compete, like swimming, diving, running, ice skating, wrestling, gymnastics, golf, tennis, skateboarding, in-line skating, biking, martial arts, and bowling, I think that swimming would be the most strenuous to play because it requires strength in specific muscle groups, endurance, and lots of power.

Your arm and leg muscles become temporarily paralyzed, which prevents you from acting out your dreams. As one ages,they sleep less of their time in REM sleep.
Some sleeping pills like benzodiazepine are rapid eye movement (REM) sleep–suppressant medications, and withdrawal often results in episodes of increased REM sleep (REM sleep rebound).
The newer hypnotics zolpidem and zaleplon are benzodiazepine-like agents, exerting effects at the same neurotransmitter GABA (Gamma-aminobutyric acid) receptors sending chemical messages through the brain and the nervous system bringing about regulation in communication between brain cells. The role of GABA is to inhibit or reduce the activity of the neurons or nerve cells.
Aside from disruption of REM sleep, sedative-hypnotic medications (benzodiazepines and non-benzodiazepines) can cause severe allergic reaction, facial swelling, memory lapses, hallucinations, suicidal thoughts or actions, and complex sleep-related behaviors like sleep-walking, sleep-driving (driving while not fully awake, with no memory of the event) and sleep-eating (eating in the middle of the night with no recollection, often resulting in weight-gain),respiratory depression in patients with pulmonary disease and may lose sleep-inducing efficacy with prolonged use.
