To observed diffraction, the size of the obstacle should be of the order of wavelength. i.e. λ=d.

Q. To observe diffraction, the size of the obstacle

has no relation to wavelength.

should be $λ /2,$ where $λ$ is the wavelength

should be much larger than the wavelength

should be of the order of wavelength

To observed diffraction, the size of the obstacle should be of the order of wavelength. i.e. $λ = d$ .
