why can astronauts float around in microgravity?\ncosmic rays\nanti - gravity suits\nlack of significant…

Brief Explanations:

Microgravity means very weak gravity. In such an environment, the gravitational force acting on astronauts is extremely small. Cosmic rays are high - energy particles from space and have nothing to do with floating. Anti - gravity suits do not exist in reality. Floating is mainly due to the lack of significant gravitational force to hold astronauts down.

Answer:

C. Lack of significant gravity
