What is most likely the purpose of an email asking for feedback about a service or product? to aguire

What is most likely the purpose of an email asking for feedback about a service or product? The options are:

A. To persuade B. To inform C. To inquire D. To entertain

The correct one is C. To Inquire. The purpose of an email asking for feedback about a service or product is to give businesses the chance to see what’s working, get discovered by new customers, and sell more. In other words, to inquire about the level of satisfaction the customer has (to tell the company if the customers are happy).

Asking for feedbacks solidifies the company´s relationship with the customer who just bought/used something. And shows them that the company cares; what the customers think, and that the company wants them to have the best experience possible. Also helps to fix what’s not working.

the fourth amendment protects:

"the right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."  

so this would mean the denial to search and seizure without warrant or permission.
