Let us take 
where V is volume and N is number of particles.
Now, for
i.e. when interparticle is much larger than the thermal de-Broglie wavelength, the gas will obey Maxwell Boltzmann Statistics.
The correct answer is: When de-Broglie wavelength is much smaller than the inter-particle distance

Explanation:
In quantum mechanics, particles are described by wave functions, and their behavior is governed by wave-particle duality. The de Broglie wavelength (λ) is a fundamental concept that relates the momentum of a particle to its wavelength, given by the equation λ = h/p, where h is Planck's constant and p is the momentum of the particle.
Classical Gas:
In classical physics, particles are treated as point-like objects without any wave nature. The behavior of a classical gas is described by classical statistical mechanics, where particles are assumed to follow classical laws of motion and obey the ideal gas equation. The classical gas model is applicable when the particles are non-interacting and their individual wavelengths are negligible compared to the inter-particle distance.
Quantum Gas:
In contrast, a quantum gas consists of particles that exhibit wave-like behavior and are subject to quantum mechanical principles. The quantum gas model is necessary to describe the behavior of particles at low temperatures or high densities, where quantum effects become significant.
Conditions for Treating a Quantum Gas as a Classical Gas:
The question asks when an ideal quantum gas can be treated as an ideal classical gas. This means that the quantum effects are negligible, and the particles can be treated as classical point-like objects. The correct answer is option B - when the de Broglie wavelength is much smaller than the inter-particle distance.
Explanation of Option B:
When the de Broglie wavelength of particles in a quantum gas is much smaller than the inter-particle distance, the wave nature of the particles becomes negligible. This is because the particles are tightly packed together, and their individual wavelengths do not significantly affect their behavior. As a result, the particles can be treated as classical point-like objects, and their behavior can be described using classical statistical mechanics.
When the de Broglie wavelength is small compared to the inter-particle distance, the wave nature of the particles is effectively "squeezed" or suppressed. The particles behave more like classical particles, following classical laws of motion and exhibiting classical statistical behavior. This allows for the use of classical gas models to accurately describe the system.
In summary, when the de Broglie wavelength of particles in a quantum gas is much smaller than the inter-particle distance, the quantum effects become negligible, and the gas can be treated as a classical gas.
