Simon learns that supplementing with water-soluble vitamins is potentially safer (compared to fat-soluble varieties) because they aren't stored in the body for as long, which reduces their ability to cause a toxicity. Which vitamin is water soluble?
1. Vitamin A
2. Vitamin C
3. Vitamin E
4. Vitamin D
5. Vitamin K

Vitamin C.

Explanation:

Vitamin C or ascorbic acid is one of the water soluble vitamin.

Other water soluble vitamins are all the members of Vitamin B group, biotin and pantothenic acid.

Water soluble vitamins  are considered as more safe to be used as supplement  without any risk of toxicity because they are easily absorbed in and excreted from our body..

Vitamin A,D, E, and K are all fat soluble vitamins.

explanation:

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.
