Answer: Option (d) is the correct answer.
Step-by-step explanation:
An ideal gas is defined as the gas for which product of pressure and volume equals to the product of number of moles, gas constant and temperature.
Mathematically, PV = nRT
where P = pressure
V = volume
n = number of moles
R = gas constant
T = temperature
Thus, we can conclude that out of the given options PV = nRT equation defines the ideal gas law.
