A)Sharper peaks at specific angles
B)Reduced peak intensity at all angles
C)Peak shifts to higher angles
D)Continuous rings of diffraction intensity✓
💡 Explanation
Because of the random orientation of crystal grains, the Bragg diffraction condition is met for all possible orientations. Therefore, a cone of diffracted intensity is formed, which appears as rings rather than discrete spots, rather than sharper peaks which would require consistent alignment.
