An imaginary gas a perfectly obeys all gas laws is called ionic gas, perfect gas, ideal gas, inert gas

The correct answer is Ideal gas.

An imaginary gas which perfectly obeys gas laws is called as an ideal gas. It is a hypothetical gas whose molecules do not occupy any space and have no interactions among themselves.

According to the combined gas laws-

Where,  

P = Pressure of gas

V = Volume of gas  

n = Number of moles

R = Gas constant

T = Temperature

Ideal gas perfectly obeys the gas law. Thus, the correct answer to the question is Ideal gas.
