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.

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
