Explanation

Option A is correct because enamel rods show a hexagonal shape and resemble fish scales when viewed in cross-section. Option B is true as the rod bodies are situated near the occlusal and incisal surfaces, with their tails pointing cervically. Option C is accurate since apatite crystals align parallel to the rod bodies and deviate by 65° from the tails. Therefore, option D, which includes all these correct statements, is the right choice.
