A gas is a form of matter that
A
has a definite volume
B
is generally a liquid or solid at room temperature
C
takes the shape and volume of its container
D
is difficult to compress
Explanation: 

Detailed explanation-1: -Liquids and gases take the shape of their containers since, they do not have definite shape and volume. Only solids have definite shape and volume.

Detailed explanation-2: -Not Volume: A liquid is the state of matter that has a definite volume but takes the shape of its container.

Detailed explanation-3: -A gas fills its container, taking both the shape and the volume of the container. Liquids and gases are called fluids because they can be made to flow, or move. In any fluid, the molecules themselves are in constant, random motion, colliding with each other and with the walls of any container.

Detailed explanation-4: -A gas has neither a definite shape nor a definite volume. Like liquids, gases are fluids. The particles in a gas can move around one another freely. If a gas is released in a closed container, the gas particles will move in all directions and spread apart as they fill the container.
