C) It has a long preganglionic fibers
Explanation:
Peripheral nervous system (PNS) is the nervous system that contains nerves and ganglia outside the central nervous system (CNS). PNS is divided into:
- somatic (voluntary) nervous system-controls the movements of the skeletal muscles
- autonomic (involuntary) nervous system-controls the smooth muscles and glands and thus it is the regulator of the major body functions. It is subdivided into tree groups:
- sympathetic ("fight and flight") system-responsible for stressful and active situations (but also in normal conditions);contains short preganglionic fibers and long postganglionic fibers.
- parasympathetic ("rest and digest") system-opposite to sympathetic, responsible for the maintenance of body's activities at rest.
- enteric nervous system-controls the function of the gastrointestinal tract.

The correct answers are B and C. The tsunami waves were as high as 500 feet, and it was triggered by a 9.1 magnitude earthquake.
Explanation:
The 2004 Indian Ocean tsunami was a series of tsunamis that swept the shores of most countries along the Indian Ocean on December 26, 2004, killing almost 280,000 people. This is considered one of the biggest natural disasters in history. The tsunami was caused by a huge 9.1 magnitude earthquake that shook the underwater off the west coast of Sumatra. This was the third largest earthquake measured by a seismometer. The ensuing tsunamis reached a height of 30 meters in some places when they made landfall. It has been confirmed that 131,028 people have died in Indonesia. More than 30,000 died in Sri Lanka and thousands died in India and Thailand. In Somalia, 4,500 km from the epicenter, 176 people were killed and about 50,000 people lost their homes. $ 14 billion in emergency aid was collected for the worst-affected countries.
