Step-by-step explanation:
The correct answer to the student's question: 'Which of the following is NOT a common challenge related to the use of the Internet of Things?' is (c) Decreased data collection. The Internet of Things (IoT) typically involves increased data collection by utilizing various internet-connected devices that collect and transmit data. The primary concerns associated with IoT are (a) Security concerns, (b) Interoperability, and (d) Privacy issues. Security concerns are a significant challenge because the network of connected devices increases the potential attack surface for cybercriminals. As such, online privacy and control also become a primary concern with the potential for sensitive personal information being exposed. Additionally, interoperability is an issue due to the need for devices from different manufacturers and with different protocols to communicate effectively.
