Final answer:
Vendors are required by law to respect the privacy of people who make Web purchases, which is true(A). Laws like COPPA protect personal data online, and data breaches have underlined the importance of such legislation.
Step-by-step explanation:
Vendors are indeed required by law to respect the privacy of people who make Web purchases. This statement is true(A). State and federal laws in the United States protect personal cyber data, including data stored electronically when making online transactions. The Children's Online Privacy Protection Act of 1998 (COPPA) is one example of legislation aimed at protecting individuals' personal information, specifically children's data on the internet. In addition to such laws, there has been an increasing concern about data breaches, with incidents at major companies like Target and JP Morgan exposing personal information and increasing the threat of identity theft. As a result, the privacy and security of online purchases have become a significant concern.
