A. The very narrow slits required would generate many different wavelengths, thereby washing out the interference pattern.
B. The two slits would not emit coherent light.
C. The fringes would be too close together.
D. In no direction could a path difference as large as one wavelength be obtained, and this is needed if a bright fringe, in addition to the central fringe, is to be observed.
