A resource block is shown in the Exhibit space of this page.

Detailed Explanation:

Rationale for Correct Answer: In Terraform, a resource type usually follows the format < provider > _ < resource_type > . In the exhibit, the resource type is aws_vpc. The prefix aws identifies the provider, and vpc identifies the resource type within that provider. Therefore, the provider is aws.

Analysis of Incorrect Options (Distractors):

A. test Incorrect. test is the value assigned to the name argument.

B. vpc Incorrect. vpc is the resource type, not the provider.

D. main Incorrect. main is the local resource name used to reference this resource in Terraform configuration, such as aws_vpc.main.

Key Concept: Terraform resource type naming convention: < provider > _ < resource_type > .
