Final answer:
Mr. Smith should read the website's privacy policy to understand the kind of information that a company collects from him during an online purchase.
Step-by-step explanation:
When Mr. Smith wants to know what kind of information the company will collect from him while he is online buying a product, he should read the website's privacy policy. This document is typically linked at the bottom of the website's homepage and provides details about how the company collects, uses, stores, protects, and shares personal data. It's important to review this document to understand the company's practices concerning user data and make informed decisions while shopping online. Although not directly listed as an option, the privacy policy is the correct resource for this type of inquiry rather than the website terms of use, product advertisement/information, product license agreement, or the product user guide.
