A. yes
B. no, because the de Broglie wavelength of the bullet is too large relative to the aperture
C. yes, because the aperture may be a slit or circular aperture
D. no, because the de Broglie wavelength of the bullet is too small relative to the aperture
D. no, because the de Broglie wavelength of the bullet is too small relative to the aperture
