• A) Yes.
• B) No, because only subatomic particles have de Broglie wavelengths.
• C) No, because a circular aperture never causes diffraction.
• D) No, because the de Broglie wavelength of the bullet is too large relative to the aperture.
• E) No, because the de Broglie wavelength of the bullet is too small relative to the aperture.
