Question

You have declared a variable named var.list, which is a list of objects, each with an id attribute.

Which expressions evaluate to a list of the objects’ id attributes?

Choose two

A [ var.list[*].id ]
B [ for o in var.list : o.id ]
C var.list[*].id
D { for o in var.list : o => o.id }

Explanation

A square-bracket for expression transforms each object into its id value, producing a tuple/list-like result. The [*] splat operator likewise iterates across all elements of a list and accesses id on each element. HashiCorp documents [for o in var.list : o.id] and var.list[*].id as equivalent expressions for this case.
