The correct options regarding the composition of Earth's core are:
**b. very dense**
**d. mostly iron**
The Earth's core is primarily composed of iron, along with some nickel and lighter elements, and it is indeed very dense. The outer core is liquid, while the inner core is solid. So while "very liquid" could be misleading in the context of the inner core, the outer core is liquid. If you need to choose the most representative elements of the core's composition, "mostly iron" and "very dense" would be the appropriate choices.
