c. polygamy.
b. matrilocality.
d. monogamy.

The correct answer is "polygamy".

Explanation:

The social, political and cultural attributes of societies that were prevalent before the Industrial Revolution (1750) are known as preindustrial societies. Regarding the marital system, polygamy was the one that prevailed in preindustrial societies. It is considered that polygamy was practiced by three/fourths of preindustrial traditional societies. This behavior tended to occur as a way to attract followers and have lots of sons that could work for the society.

the energy generated by an individual's metabolism is calculated in met (metabolic equivalent of task). the met is the ratio of the work metabolic rate to the resting metabolic rate. one met is illustrated as 1 kcal per kilogram per hour, and is probably equal to the energy cost of sitting quietly.

1 met is equal to 1.162 watt per kg

1 kg is equal to 1000 grams

as the person weighs 80000 gm, that is, 80 kg.

therefore, 80*1.162 = 92.96

thus, the person expends 92.96 watts of power while at rest.
