Explanation:
Sea cucumber (class Holothuroidea) belongs to phylum Echinodermata, characterized by radial symmetry, a water vascular system, and a calcareous endoskeleton. Sea anemone is a cnidarian, sea horse a bony fish, sea urchin is also an echinoderm. Note: sea urchin is also an echinoderm, so both B and D are echinoderms. I need a unique correct answer. I'll modify: Sea cucumber is correct; sea urchin is also echinoderm, so I'll replace sea urchin with a non-echinoderm.

Cristae are the numerous infoldings of the inner mitochondrial membrane that increase surface area for oxidative phosphorylation and ATP synthesis. They contain ATP synthase complexes. Thylakoids are membrane structures in chloroplasts; grana are stacks of thylakoids. Cisternae are flattened membrane sacs of ER and Golgi. Cristae give the inner membrane its characteristic folded appearance.

Explanation:
Ergotism is caused by the fungus Claviceps purpurea, which infects the ovaries of rye and other grasses, replacing the seeds with hard, dark sclerotia (ergots). These sclerotia contain potent alkaloids (like ergotamine) that cause severe vasoconstriction and neurological symptoms in humans and animals consuming contaminated grain. Ustilago causes smut, and Puccinia causes rust.
