Which of the following is not true of Terraform providers?

• A. Providers can be written by individuals
• B. Providers can be maintained by a community of users
• C. Some providers are maintained by HashiCorp
• D. None of the above

Answer: (D)

Terraform providers are plugins that extend Terraform with resource types and data sources for different platforms and services. They can be authored by individuals who publish a plugin, or by a community of users who collaborate on open-source provider projects. Some providers are maintained by HashiCorp as official offerings. Since all of these statements are true, the option that says none of the above is not true is the best choice. In short, you can write providers, communities maintain providers, and HashiCorp maintains some providers, which is why none of the listed statements is false.
