 An azeotropic mixture is a type of mixture that boils at a constant temperature and has the same composition in both liquid and vapour phases. Option A, which is a mixture of ethanol and water, forms an azeotropic mixture at 95.6% ethanol and 4.4% water. Option B, which is a mixture of hydrogen chloride and water, forms an azeotropic mixture at 20.24% hydrogen chloride and 79.76% water. Option C, which is a mixture of nitric acid and water, forms an azeotropic mixture at 68% nitric acid and 32% water.

Therefore, all of the above options (A, B, and C) are examples of azeotropic mixtures. Hence, the correct answer is option D.
