Which describes iodine in solid form?

Explanation:
Iodine in solid form is a dark, shiny crystal that looks grey, often described as grey with a metallic sheen. The purple color is seen in iodine vapour when it sublimes, not in the solid itself. So describing solid iodine as grey fits what the solid actually looks like, while purple, black, or orange do not describe its solid form.
