Icefish live in very cold waters (-1.8 degrees celsius) where temperatures are below blood's freezing point. which statements are true about icefish adaptations for cold water?

I found following two statements true for why ice fish live in cold environment.

A. Ice fish have antifreeze proteins, it inhibits blood from freezing.

B. Ice fish do not have red blood cells, which reduces the viscosity of blood, allowing it to flow more freely at cold temperatures.

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.
